The Dimensionally Extended 9-Intersection Model (DE-9IM) is a topological model and a standard used to describe the spatial relations of two regions (two geometries in two-dimensions, R 2), in geometry, point-set topology, geospatial topology, and fields related to computer spatial analysis.
Some GIS software, such as ArcGIS Pro, natively supports this model, with functionality including animation. Time-stamped boundaries , using the topological vector data model to decompose polygons into boundary segments, and stamping each segment by the time during which it was valid.
Plugins are provided for Autocad (for designers), ArcGIS, open source QGIS (for analysts & designers) and as a standalone Python version that works on 2D or 3D shapefiles enabling use in other GIS software and custom projects. sDNA standardizes on the network link as a unit of analysis, and computes a wide variety of closeness, betweenness ...
The simplest model is to assume the earth is a perfect sphere. As more measurements of the earth have accumulated, the models of the earth have become more sophisticated and more accurate. In fact, there are models called datums that apply to different areas of the earth to provide increased accuracy, like North American Datum of 1983 for U.S ...
In 2023, Meta's AI research released Segment Anything, a computer vision model that can perform image segmentation by prompting. As an alternative to text prompts, Segment Anything can accept bounding boxes, segmentation masks, and foreground/background points. [75]
To the right of those objects are milepoints of the endpoints of the particular route segment on which you clicked. In most cases, if you click on a highway segment "after" the intersection of interest (based on the inventory direction, i.e., north for north–south highways), the From Mile figure will be the number you are looking for.

ArcObjects is a library of Component Object Model (COM) components that build up the foundation of Esri's ArcGIS platform. ArcObjects is written primarily in the C++ programming language. Since ArcGIS is completely built on top of ArcObjects, the ArcGIS platform can be fully customized and extended by making use of its COM services and ...
