Getting a boundingbox into FME 2012

How many times have this happened to You? 1. You need a boundingbox. Possibly to query a database or maybe call a WMS service. 2. You open a map somwehere on the internet or maybe in another GIS-tool than FME. 3. You locate Your area of interest and manually note of the corner coordinates -the […]

Map Trawling the Web – the unusual way to geographic information

MapTrawler While experimenting with, more than a year ago, I came up with an interesting search method, “Map Trawling.” In short the method can be described as: Find out placenames within a certain area. Feed all these placenames as keywords into a search-engine. The result is: Geographic information, Maps, Transit information, Municipal plans, Tourist […]

Using FME and OSM to create Li(E)DAR

Would You like to play around with LiDAR and FME? Have no data for testing? By using the “OSM Extractor” to get OSM data (buildings+roads) and combining it with SRTM data I’ve come up with something that (sort of) looks like LiDAR data. By applying the PointCloud trix by Dmitri at Safe I produced LAS […]

Lots of FME for extracting OSM-data!

Today I decided to examine if someone actually use our FLASH-application “OSM Extractor“. In short it’s a map with a simple user-interface to generate a Workspace for FME. The workspace is setup to extract OSM-data with the current bounding-box. (You can read more in the instructions). I was quite surprised to see that it’s used […]

New FME Atlantis transformer

Soon it’s over for one of the greatest achievements in mankind history. The last mission will be STS-135 for the space shuttle. As a space-nerd I will really miss this icon. Creating a custom transformer in FME (called Atlantis) is my goodbye to the shuttle. The transformer renders a PointCloud by using an embedded 3D-model […]

World Wide Podcast – FME 2011 Launch

1 hr recording from the FME 2011 launch – As FME 2011 was launched in March the Safe Software crew took of for an epic World tour. The liftoff was in Vancouver. Some of us could not go there. But we did follow the  livestream (of great qualit by the way. Check out the […]

Finally: Using the FocalLength in FME

Thanks to Graeme’s fantastic optical writeup I finally created a Workbench in FME. (Actually “Workspace” is the correct expression but rarely used…..) * For distance to the picture I decided to go with Graeme’s formula “(@Value(jpeg_exif_focallength) * 659.065) / 1000” * However, I did implement a formula “(4.1-0.0330*@Value(jpeg_exif_focallength))” for the width of the picture. * […]

FME GPS Camera and FocalLength results

Preliminary results Here are som charts for the Tennisball test. We can clearly see that the distance to the picture is NOT a linear function. * Using no zoom (FocalLength 4.25 mm) means approx 3m to the picture (middle tennisball) * Using 6.4 zoom (FocalLength 27 mm) means approx 16-17 m to the picture (middle […]

FocalLength with FME – I challenge Camera Nerds

I need to use Focallength but it’s tricky. In my previous blog-post I confessed that I never really quite understood all the technical lingo with SLR Cameras. Today I realized that positioning pictures in 3D with FME still demands some knowledge about photo-lingo. Good thing I studied remote sensing 15 years ago then… So understanding […]
