This is the beautiful building in from of my house in Nantes… Let’s model it first using Sketchup. Also I have used a non standard style only for visualization purposes… If we have the North behind us this means we are going to have a lot of light… but so far we are just guessing… Now weContinue reading “Solar + Shadows analysis on Rue Massillon, Nantes (France)”

Shadow analysis en Puerta de Arganda, Madrid.
Hoy publico en español puesto que los datos son en español y yo soy español:-) but if you guys have any doubt dont hesitate to ask… even if you are french I will be around to answer you back “en français”, quand même !!!. La idea era hacer un estudio de sombras de para mi propio usoContinue reading “Shadow analysis en Puerta de Arganda, Madrid.”
On va déménager alors… Analyse solaire !!!
Ma copine et moi on va nous déménager très bientôt alors il faut faire une analyse solaire. Nantes, la ville ou on habite est connue dans le monde entier pour ses niveaux de pluie, n’importe que ce soit été, printemps… meme si France Météo a dit qu’il va faire BEAU… A Nantes ça ne marcheContinue reading “On va déménager alors… Analyse solaire !!!”

Architectural models and some fun
I started sketching this building across the street and decided to include some funny pseudo 3D pictures of my girlfriend and myself… Architectural modelling is easy using Sketch-up. This model took me about 5 hours work (during the weekend, shame!), using components, texturing, handling scenes and exporting/editing Video. Hope you guys like it.
ViewTec’s State-of-the-art 3D visualization
Good news!!!! They’ve probably released this Geovisualization Engine long time ago (It used to be an ‘in-house’ software) but I have just realized. I worked with this state-of-the-art TerrainView 3D software for six months while I was working as a GIS Specialist in Cape Town (South Africa)… What does this software has that no oneContinue reading “ViewTec’s State-of-the-art 3D visualization”
Smarter Streets: Case Studies for Cities and Utilities – Learn How the City of Baltimore and Washington Gas Reduced Costs
In the City of Baltimore, the decades-old infrastructure consists of 2,000 miles of roads, 300 bridges and culverts, 7,600 miles of water pipes, storm water drains and wastewater lines, and 3.7 million feet of conduit. Washington Gas serves more than one million residential, commercial and industrial customers throughout the Washington, DC metropolitan area. What theyContinue reading “Smarter Streets: Case Studies for Cities and Utilities – Learn How the City of Baltimore and Washington Gas Reduced Costs”
Visualizing LAS LIDAR data with sketch-up
While trying to figure out the way to get a 3D model from raw Lidar data, I first opened my LAS file in Global Mapper, exported it to DXF, imported then into Sketch-up and after recording a few scenes, I saved the animation… this is it!. Alberto
Using Excel to calculate the RMSE for LiDAR vertical ground control points
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 the reporting function built-in. However, plain Microsoft Excel can also do the job (except for extracting the elevation from the LiDAR data).
Data acquisition: How do I know if this river is been well acquired?
I’ve already entered my river but my imagery was in 2D so… was it well acquired?… First of all, I import my shape (shp) file into Global Mapper (what a great sofware!) and export my vector file as a KML. Import my river.kml file into my brand new Google Earth 5.2 or just double-click itContinue reading “Data acquisition: How do I know if this river is been well acquired?”
