Running in Madrid. A GIS approach!

these density maps performed in Global Mapper overlay the geometry lines saved out my running application (Garmin Connect). and once they are exported to points, i can generate a density map, chosing an easy to understand legend and i overlay to Google Earth so its also easy to be sent if needed be (why for? i don’t know!).

Euclidean allocation analysis II

Imagine you need to promote recycling.

You need to service them all properly but you can only choose 5 shops (out of the […]

DTM from SRTM? Let’s compare sources using RMSE (Root Mean Square Error) and a gaussian kernell density map

I guess we all can make a DTM out of many sources but SRTM is one of the most common ones, right?. Then let’s learn from this very simple approach how close we are from the SRTM raw data. Selecting a not very big representative area to be able to handle it, exporting raster to polygon (from […]
