A way to generate random/fake sensor data
Geographic Information SystemsHow do you generate dummy data? For most program modifications, the process looks like the following: Set up a test environment in the DBMS. Implement the modification in the test environment. Use the copied live data as dummy data. Activate the modification in test. Fix bugs. Go live with the program modification on live data.
Using Mapbox tiles with folium
Geographic Information SystemsAre tile styles of Folium maps? Layers and Tiles in Folium Each tileset has a different way of representing data in the map. Folium allows us to create maps with different tiles like Stamen Terrain, Stamen Toner, Stamen Water Color, CartoDB Positron, and many more. By default, the tiles are set to OpenStreetMap. What are
Creating custom projection using provided Helmert Parameters and ArcMap?
Geographic Information SystemsHow do I create a custom projection in Arcmap? Answer Open ArcToolbox and select Data Management Tools > Projections and Transformations > Define Projection. Choose the appropriate coordinate system. You have to define it as what it is, not as what you want it to be. Once the projection is defined correctly, the projection can
How to hand over polygon attribute to new point while digitizing?
Geographic Information SystemsHow do I edit an existing polygon in QGIS? Editing Polygons or Lines is similar to editing Point features, except that there will always be “segments” or “arcs” connecting the vertexes involved. Go to any POLYGON layer that you want to practice editing. Right-click on the Layer in the Layers Panel and select TOGGLE EDITING.
