geojson-to-shpfile

# geoJSONToShpFile This code converts GeoJSON to shape files. Please keep in mind that the current code expects the common geoJSON format with features list. The code will not work if you do not have the features list. The following example is OK since it has a features list with three points. One more important comment, shapefiles can hold only one feature type e.g. points, lines, and polygons. For that, I decided that the code will grab only features similar to the first feature in the list. In geoJSON, you can have different feature types in one feature list, and that does not work with shape files. { "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": {"id": 1, "name": "Indian Ocean" }, "geometry": { "type": "Point", "coordinates": [ 80.15625, -22.91792293614602 ] } }, { "type": "Feature", "properties": {"id": 2, "name": "Atlantic Ocean" }, "geometry": { "type": "Point", "coordinates": [ -37.96875, 17.644022027872726 ] } }, { "type": "Feature", "properties": {"id": 3, "name": "Pacific Ocean" }, "geometry": { "type": "Point", "coordinates": [ -164.1796875, 1.4061088354351594 ] } } ] }

geospatial-footprints

# geospatial_footprints This code is for my dissertation's focus. The purpose is to geoparse text and creating geospatial footprints based on place names found in text and their spatial orientation. There are 15 different types of geospatial footprints for instance: 1. A footprint for an incedent between two buildings 2. A footprint for an incednet along a road and close to a building 3. A footprint for an incedent on a road segment between two segments There is a sample GeoJSON file for some of the place names in George Mason University, Fairfax campus. You can try the code by using the following Some test messages: 1. curb crack between the fenwick library and the JC building. 2. Steep stairs on the northern side of innovation hall. 3. A maintenance site on sager ave between university dr and east st Technologies used in this code are: Bootstrap, MapBox, and TurfJS

psycopg2-gdal-raster-val-to-pnts

The code assumes you have a proper raster file and a point table in Postgres, and both are in the same projection. The code uploads the raster file into Postgres using the raster2pgsql command. Then it will create a copy table of the point table with an additional column called rast_val. This new column is then updated with pixel values intersecting with the points.
