kandi X-RAY | jsts Summary

jsts is a JavaScript library typically used in Geo, Map applications. jsts has no bugs, it has no vulnerabilities and it has medium support. However jsts has a Non-SPDX License. You can install using 'npm i smap-jsts' or download it from GitHub, npm.

JSTS is an ECMAScript library of spatial predicates and functions for processing geometry conforming to the Simple Features Specification for SQL published by the Open Geospatial Consortium. JSTS is also a port of the well established Java library JTS. The primary goal of the project is to provide web mapping applications with a complete library for processing and analyzing simple geometries but JSTS can also be used as a free standing geometry library. JSTS was made using automatic translation of the original JTS Java source via AST to AST transformation preserving the JTS API, except for the I/O related classes which has been selectively and manually ported with support for WKT, GeoJSON and OpenLayers 3+. A Google group is available for discussions. A port of JTS Validation Suite provides additional tests.

            Check overlapping of Polygon using JSTS with a GeoJson File
            Asked 2021-Mar-13 at 16:26

            I am trying to alert user while drawing polygon over Google Maps with pre rendered Polygons using geoJson. Whenever polygon is drawn over existing Polygons, user should get alert. I got an example but it works for the polygons on the same layer (Fiddle Example). My Code is hosted here. Refer the image below that I need:

            One option would be to parse the polygons from the GeoJSON to "normal" google.maps.Polygon objects, then preload those to your all_overlays array:

            Change colour of buffers in openlayers
            Asked 2021-Mar-05 at 22:09

            I have the following JS code to create a 1 mile buffer in Openlayers using JSTS. However, I'd like to add 2 or 3 buffers but change the colour from the default for easier viewing.

            So far, I've tried this as this styling as changed the fill/stroke of my points before

            As @Mike indicated in his comment: "The image option in ol.style.Style is used to style point features with an icon or regular shapes such as a circle. Your buffered geometry is a polygon, and is styled by stroke and fill options of ol.style.Style"

            Change the style:
