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 (fromContinue reading “DTM from SRTM?

Some of my 3D scenarios

Barcelona (Spain), Winnipeg (Canada), Las Vegas (USA), Moscow (Russia), Durban (South Africa), Vancouver (Canada) and Tokyo (Japan)… these were some of my Terrain view’s 3D scenarios published by Computamaps, a South African company I worked in not so long ago. By the way it was one of my best professional experiences ever… I enjoyed joiningContinue reading “Some of my 3D scenarios”

One more 3D building. Avenida de la Vega 28108. Restaurante Asiático SHENG. Madrid, Spain.

I used to have lunch every thrusday there, at the ‘Restaurante Asiático SHENG’. I strongly recommend you ‘entremeses’ (In China you will find them as ‘dim-sum’) and Cantonese duck or Hong Kong duck (this was slightly spicy thou).  Very good food, very fast service and pretty cheap menu: 10,7 €… ideal for an IT worker!. TheseContinue reading “One more 3D building. Avenida de la Vega 28108. Restaurante Asiático SHENG. Madrid, Spain.”

News: Lufthansa Realtime 3D Airtraffic

I have just read a very interesting item of news. WHITEVOID has just released a 3D visualization engine for monitoring more than 16.000  Lufthansa airplanes in realtime… amazing, isn’t it?. You can navigate throughout the world in a 3D 14 meters screen (!) while you filter content and adjust size, speed and any other parameter… InContinue reading “News: Lufthansa Realtime 3D Airtraffic”

Creating and personalizing KML code (placemarks).

First of all, what is KML?. KML is a file format used to display geographic data in an Earth browser, such as Google Earth, Google Maps, and Google Maps for mobile. You can create KML files to pinpoint locations, add image overlays, and expose rich data in new ways. KML is an international standard maintained byContinue reading “Creating and personalizing KML code (placemarks).”

News: Capaware, an opensource 3D geographical Multilayer Framework… First steps…

I discovered this project a few months ago and I’ve been following them very close. It’s always very interesting for freelancers and self taught professionals having an opensource 3D framework to start building your own scenaries not needing to pay a big amount of money for a license… I will do my best to upload here myContinue reading “News: Capaware, an opensource 3D geographical Multilayer Framework… First steps…”
