CARTOGRAPHY AND GEOGRAPHIC INFORMATION SCIENCE, 2024

By deploying remotely sensed data together with spatial statistical modeling, we use regression modeling to investigate the relationship between the density of the built environment and two types of crime. We show how the Global Human Settlement Layer (GHSL) data set, which is a measure of building density generated from Sentinel 2A satellite imagery, can be used to create different indexes to describe the built environment for the purpose of analyzing crime patterns for indoor crimes (residential burglary) and open space crimes (street theft). Analysis is at neighborhood level for Stockholm, Sweden. Modeling is then extended to incorporate six planning areas which represent different neighborhood types within the city. Modeling is further extended by adding selected social, economic, demographic and land use variables that have been found to be significant in explaining spatial variation in the two crime categories in Stockholm. Significant associations between the GHSL-based indexes and the two crime rates are observed but results indicate that allowance for differences in neighborhood type should be recognized. Average income and transport hubs were also significant variables in the investigated crime categories. The article provides a practical demonstration and assessment of the use of high-resolution satellite data to examine the association between urban density and two common types of crime and offers reflections about the use of satellite image data in crime analysis. Key policy highlights • Data Quality and Standardization: Encourage the testing and standardization of methods and measures using remote sensing data, in particular satellite imagery, as a basis for research on urban crime and practical use in urban safety interventions. • Open Access to Data: Push for policies that promote open access to remote sensing data in research and practice, especially satellite imagery. This is of particular importance in resourcepoor urban environments, especially in countries of the Global South where official statistics are not available or are not regularly updated. Open data, such as the one used in this study, provides evidence, fosters innovation, and is the basis for sustainable urban governance. • Evidence-Based Resource Allocation: Highlight the importance of using remote sensing data and methodologies to inform resource allocation decisions in law enforcement agencies. Advocate for policies that prioritize data-driven strategies to address crime concentrations and allocate resources efficiently.

A geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on Earth’s surface. By relating seemingly unrelated data, GIS can help individuals and organizations better understand spatial patterns and relationships.

GIS technology is a crucial part of spatial data infrastructure , which the White House defines as “the technology , policies, standards, human resources, and related activities necessary to acquire, process, distribute, use, maintain, and preserve spatial data .”

GIS can use any information that includes location . The location can be expressed in many different ways, such as latitude and longitude , address, or ZIP code .

Many different types of information can be compared and contrasted using GIS. The system can include data about people, such as population , income , or education level. It can include information about the landscape , such as the location of streams, different kinds of vegetation , and different kinds of soil . It can include information about the sites of factories, farms , and schools, or storm drains , roads , and electric power lines .

With GIS technology , people can compare the locations of different things in order to discover how they relate to each other. For example, using GIS, a single map could include sites that produce pollution , such as factories, and sites that are sensitive to pollution , such as wetlands and rivers . Such a map would help people determine where water supplies are most at risk.

Data Capture

Data Formats

GIS applications include both hardware and software systems. These applications may include cartographic data , photographic data , digital data , or data in spreadsheets.

Cartographic data are already in map form, and may include such information as the location of rivers , roads , hills , and valleys . Cartographic data may also include survey data and mapping information that can be directly entered into a GIS.

Photographic interpretation is a major part of GIS. Photo interpretation involves analyzing aerial photographs and assessing the features that appear.

Digital data can also be entered into GIS. An example of this kind of information is computer data collected by satellites that show land use —the location of farms , towns , and forests .

Remote sensing provides another tool that can be integrated into a GIS. Remote sensing includes imagery and other data collected from satellites , balloons, and drones .

Finally, GIS can also include data in table or spreadsheet form, such as population demographics . Demographics can range from age, income , and ethnicity to recent purchases and internet browsing preferences.

GIS technology allows all these different types of information, no matter their source or original format, to be overlaid on top of one another on a single map. GIS uses location as the key index variable to relate these seemingly unrelated data.

Putting information into GIS is called data capture . Data that are already in digital form, such as most tables and images taken by satellites , can simply be uploaded into GIS. Maps , however, must first be scanned , or converted to digital format.

The two major types of GIS file formats are raster and vector. Raster formats are grids of cells or pixels . Raster formats are useful for storing GIS data that vary, such as elevation or satellite imagery . Vector formats are polygons that use points (called nodes ) and lines. Vector formats are useful for storing GIS data with firm borders , such as school districts or streets.

Spatial Relationships

GIS technology can be used to display spatial relationships and linear networks. Spatial relationships may display topography , such as agricultural fields and streams. They may also display land-use patterns, such as the location of parks and housing complexes.

Linear networks, sometimes called geometric networks, are often represented by roads , rivers , and public utility grids in a GIS. A line on a map may indicate a road or highway. With GIS layers, however, that road may indicate the boundary of a school district , public park, or other demographic or land-use area. Using diverse data capture , the linear network of a river may be mapped on a GIS to indicate the stream flow of different tributaries.

GIS must make the information from all the various maps and sources align , so they fit together on the same scale . A scale is the relationship between the distance on a map and the actual distance on Earth.

Often, GIS must manipulate data because different maps have different projections . A projection is the method of transferring information from Earth’s curved surface to a flat piece of paper or computer screen. Different types of projections accomplish this task in different ways, but all result in some distortion . To transfer a curved, three-dimensional shape onto a flat surface inevitably requires stretching some parts and squeezing others.

A world map can show either the correct sizes of countries or their correct shapes, but it can’t do both. GIS takes data from maps that were made using different projections and combines them so all the information can be displayed using one common projection.

Once all the desired data have been entered into a GIS system, they can be combined to produce a wide variety of individual maps, depending on which data layers are included. One of the most common uses of GIS technology involves comparing natural features with human activity.

For instance, GIS maps can display what man-made features are near certain natural features, such as which homes and businesses are in areas prone to flooding .

GIS technology also allows users to “dig deep” in a specific area with many kinds of information. Maps of a single city or neighborhood can relate such information as average income , book sales, or voting patterns . Any GIS data layer can be added or subtracted to the same map .

GIS maps can be used to show information about numbers and density . For example, GIS can show how many doctors there are in a neighborhood compared with the area’s population .

With GIS technology , researchers can also look at change over time. They can use satellite data to study topics such as the advance and retreat of ice cover in polar regions, and how that coverage has changed through time. A police precinct might study changes in crime data to help determine where to assign officers.

One important use of time-based GIS technology involves creating time-lapse photography that shows processes occurring over large areas and long periods of time. For example, data showing the movement of fluid in ocean or air currents help scientists better understand how moisture and heat energy move around the globe.

GIS technology sometimes allows users to access further information about specific areas on a map . A person can point to a spot on a digital map to find other information stored in the GIS about that location . For example, a user might click on a school to find how many students are enrolled , how many students there are per teacher, or what sports facilities the school has.

GIS systems are often used to produce three-dimensional images. This is useful, for example, to geologists studying earthquake faults .

GIS technology makes updating maps much easier than updating maps created manually. Updated data can simply be added to the existing GIS program. A new map can then be printed or displayed on screen. This skips the traditional process of drawing a map , which can be time-consuming and expensive .

People working in many different fields use GIS technology . GIS technology can be used for scientific investigations, resource management , and development planning.

Many retail businesses use GIS to help them determine where to locate a new store. Marketing companies use GIS to decide to whom to market stores and restaurants, and where that marketing should be.

Scientists use GIS to compare population statistics to resources such as drinking water. Biologists use GIS to track animal- migration patterns.

City, state, or federal officials use GIS to help plan their response in the case of a natural disaster such as an earthquake or hurricane . GIS maps can show these officials what neighborhoods are most in danger, where to locate emergency shelters, and what routes people should take to reach safety.

Engineers use GIS technology to support the design, implementation, and management of communication networks for the phones we use, as well as the infrastructure necessary for internet connectivity. Other engineers may use GIS to develop road networks and transportation infrastructure .

Neogeography Neogeography is a controversial term that often describes user-generated location data or “citizen geographer” platforms. Neogeography may describe projects as varied as the massive collaborative effort of OpenStreetMap and auto-generated location tags in social media.

Photozincography The labor-intensive process of photozincography anticipated GIS in the 19th century. This process used zinc plates to draft different layers of a map, and a large-process camera to combine the layers into a single image.

GIS: What is it? • The key to all data in a GIS is that it is • georeferenced, meaning it has a known • location. • All information in a GIS has an attribute • (What it is.) and a location (Where it is.) • GIS is ultimately a problem solving/decision • making tool.

GIS: Database Structure • A GIS database is comprised of layers • (themes) and attributes • Example: Layer-Forest cover • Attributes-tree species (overstory) • -height (m) • -canopy closure (%) • -understory species • -age • Can you think of attributes for a “roads” layer?

GIS: Database Structure • Information in a GIS is stored in four ways, • depending on the feature. • Points: hospitals, oil wells, phone booths • Lines: roads, streams/rivers, railroads • Polygons (Areas): crop fields, forest stands • Pixels: for raster-based GIS

GIScience • Geographic Information Sciences • GIS is only one discipline of GISciences-the • analysis, problem solving, decision making, • and modelling • How do we get the data into a GIS?. . . • This is where GIScience becomes important

GIScience • Cartography-the art and science of map • making • Geodesy-the science and accurate measurement of the earth • Surveying-the science and accurate measurement of natural and man- • made features on the Earth • Photogrammetry-the science of • measurement from • photographs and images

GIScience • GPS-the accurate collection of positional • information • Laser Altimetry-the accurate measurement • of height from the air • (trees, buildings, etc.) • Remote Sensing-the science of Earth • observation from space • Image Processing-the science of analyzing • imagery to gain useful • information

Add a new presentation to a project

A presentation is a collection of pages that can interactively display the maps or scenes in a project—along with supporting descriptive text, images, or videos—in a full-screen manner. They are stored in the project and listed as items in the Presentation folder category of the Catalog pane. A presentation opens in a presentation view where you can add and organize the pages to include in the presentation. You can share and export a presentation as a PDF, a folder of images, or a video file.

• Show an updated design proposal for a new development.
• Highlight the analysis results of a recent investigation.
• Update field officers or supervisors with current status information.

A presentation is composed of any combination of four types of pages: map pages, blank pages, image pages, and video pages. Only one page is shown at a time in a presentation view but all pages are visible as thumbnails in the Page Order view of the Contents pane of a presentation view.

To add a new presentation to a project, complete the following steps:

A new empty presentation opens in a presentation view.

The new page opens in the presentation.

• To add elements to the page, click the Insert tab and choose an element from the gallery in the Elements group.
• In the Contents pane, click Insert Page again to create additional pages in the presentation.
• Expand the Presentations folder node in the Catalog pane to manage the presentations in the project. You can view and edit metadata; export, remove, copy, or open the presentation; and access properties for the presentation.

Three-dimensional web-based client presentation of integrated bim and gis for smart cities.

1. Introduction

2. literature review, 2.1. 3d city modeling.

• Design Process
• Environmental Analysis
• Building Construction Process
• Building Operation

2.3. Integration of GIS-BIM

2.4. gis-bim integration challenges.

• Semantic Transformation
• Geometric Transformation
• Representation Transformation
• Georeferencing
• Level of Detail Transformation

2.5. 3D Web Client

• Performance and Scalability: Cesium is known for its ability to handle large data sets efficiently, Cesium utilizes techniques like level-of-detail (LoD) and culling to optimize rendering performance [ 64 ], and while other 3D web presenters offer similar capabilities, Cesium often excels in terms of overall performance and scalability, especially when dealing with complex 3D scenes.
• Feature Richness: Cesium provides a comprehensive set of features, including support for various data formats (e.g., GeoJSON, KML, WMS), 3D terrain, real-time data visualization, and integration with popular mapping APIs (e.g., Google Maps, OpenStreetMap) [ 64 ]. While other viewers may offer comparable features, Cesium’s feature set is often considered more extensive and well-integrated.
• Open-source Community and Ecosystem: As an open-source project, Cesium benefits from a large and active community of developers who contribute to its development and provide support. This community fosters innovation and ensures the library’s continued growth [ 64 ]. While other viewers may support 3D Tiles to some extent, Cesium’s implementation is often considered more robust and efficient.
• 3D Tiling Support: Cesium’s native support for 3D Tiles, a standardized format for streaming massive geospatial data sets, makes it well-suited for large-scale 3D visualization projects [ 64 ], and while other viewers may support 3D Tiles to some extent, Cesium’s implementation is often considered more robust and efficient.
• Integration with Other Technologies: Integrates seamlessly with other web technologies, including HTML5, WebGL, and JavaScript frameworks like React and Angular. This flexibility allows developers to easily incorporate Cesium into existing web applications [ 64 ], while other viewers may have limitations in terms of integration with other technologies, making them less versatile for developers.

2.6. Data Security

• Security by Design: Incorporate security into the development process from the beginning, rather than as an afterthought.
• Regular Security Audits: Conduct regular security audits to identify vulnerabilities and assess compliance with security standards.
• User Education: Educate users about security best practices, such as strong password management and avoiding phishing attempts.
• Incident Response Plan: Have a plan in place to respond to security incidents promptly and effectively [ 69 ].
