Converts a bounding box to geohashes
//Converts a bounding box bounded by minLat and maxLat and minLng and maxLng to a list of geohashes (e.g. ["60;24/19/84", "60;24/19/85"]) used for MQTT topic filters

C# routing application for calculating a set of shortest paths from a series of predefined start and end locations. Each start node can be assigned an integer load value which accumulates on its corresponding end node. In order to compile this code, download and reference NetTopologySuite, an open source spatial analysis library, and QuickGraph,…
