Hi guys, Surfing the internet is great when you need to figure out something. I needed to validate some DTM from unknown sources against an also unknown source (but at least a kind of reliable one, Google Earth). All we need is Google Earth TCX converter ARcGIS Excel This is the procedure i have followed:Continue reading “DTM validation using Google Earth (and RMSE extraction)”
(source: http://dominoc925.blogspot.com/) The height accuracy of the collected LiDAR data can be verified by comparing with independently surveyed ground control points on hard, flat, open surfaces. It is essentially just calculating the height differences for all the control points and then determining the height root mean squared error (RMSE) or differences. Most LiDAR processing software have theContinue reading “Using Excel to calculate the RMSE for LiDAR vertical ground control points”
My very good friend Fernando (a spanish/english like friend of mine:-)) introduced me this magnificent route planner he was using at that moment (three years ago!!!!)… map24.com had a very interesting 3D engine, very easy to use and very reliable… I’ve been using it since but it has never been one of the most famousContinue reading “Map24.com; My favorite route planner!”
Please, dont forget to turn on your speakers. Even if i first used a different score and Youtube’s elfs told me not to use it (because of copyright authoring) I have chosen this music from their stuff and this is what I finally got… Hope you like it.

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”
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.
