Stereo aerial image interpretation: LPS Stereo or Stereo Analyst for ERDAS IMAGINE?
By barbara....@wsl.ch in ERDAS Software Forum

Hi,

we are doing stereo aerial image interpretation and extracting 3D data. Could anyone tell me which product will be better suited for it:

• LPS Stereo or
• Stereo Analyst for ERDAS IMAGINE?

Here are the basic requirements for our application:

• Display more than 1 Stereo Views. We must have at least 2 Stereo Views with different images (different flight years) open
• Support of ADS40/80 and RC30 images
• Display labels or annotation on top of stereo images
• Following actions need to be performed programmatically
  
  • Load stereo images
  • Set ground point (i.e. setting the cursor position (x, y, and z))
  • Get ground point (i.e. getting the cursor position (x, y, and z))
  • Set scale and extent of all the Stereo Views

Thanks,

Barbara

LPS Stereo just enables stereo view in control point measurement etc. It is not a stereo mapping application just enables stereo view in certain LPS fucntions. The comparizon of products is then as I see:

LPS TE is a terrain editor tool for LPS. It contains streo view and stereo mapping but just for terrain features. No buildings etc.

OR

The real stereo mapping applications what exists in Erdas are

• Stereo Analyst for Erdas Imagine
• Stereo Analyst for ArcGIS
• Pro600 for Microstation
• Pro600 Fundamentals for Bentley Powermap.

These are really the choises you have in case pure Terrain mapping offered in TE is not enough - or your needs are not fulfilled with LPS Stereo capability that really offers you a stereo view capabilities in control point measurement tool.

 

The choise depends on your needs and platforms. My opinion is that Erdas based Stereo Analyst for ArcGIS is clearly a highlight of stereo mapping tools we have but it depends on your normal platform and experience. I have been using ArcGIS for a long time and that is why it feels more familiar to me rather than going to Microstation.

YOu can see descriptions of each products in Erdas webiste products section.

And as a additional info I have a feeling that due new viewing platform shown in Erdas Labs I excpect some unification of these tools in future. We have at the moment so many different stereo mapping platforms that unifying of them is coming within next versions.I hope in future choice will be much easier than today.
