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?”

GIS+Architectural scenaries. Awesome!

Even from scratch or from dgn/dxf vectorial format’s contour lines you create your own scenario. Then import your model previously created using Sketch-up (this time i used google’s 3d warehouse, thank you Dilbert). Stamp your house using sketch-up sandbox tools. Then fur your scenario as if it was grass… A little of photoshop like clouds andContinue reading “GIS+Architectural scenaries. Awesome!”

Map24.com; My favorite route planner!

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!”

Interesting: sketchup, more than a quick visualization tool.

I’ve extracted this information from the very interesting ‘Sketchup blog’ from Google… They talk about something I have always thought it could happen… Sketchup is not only a rapid visualization tool but a CAD like software with visuallization capabilities which in addition is integrated within a world wide used 3D scenary, perfect for Geovisualization andContinue reading “Interesting: sketchup, more than a quick visualization tool.”

ComputaMaps completes 3D Digital Models of stadiums hosting the 2010 FIFA World Cup in South Africa

Hi there, let me please show you guys my latest 3D job. I assume mine is the worst among these incredible 3D models created by my argentinian colleague Lisandro Baibiene (and very good friend by the way) …but I am proud they counted on me and allow me to join this winning team… hurray SouthContinue reading “ComputaMaps completes 3D Digital Models of stadiums hosting the 2010 FIFA World Cup in South Africa”

Ever tried Google Earth 3D Building Maker?

I started modelling 3D buildings quite a few years ago, I used to use 3D StudioMAX… After almost forgetting everything i knew about modelling, 3D and so on Sketch up was released by Google. In a few days i was not just making demos but working and producing!!! Its extremly easy!!!!. Now They have justContinue reading “Ever tried Google Earth 3D Building Maker?”
