Hi, I'd like to convert my ers imagery from Mercator projection (x,y) to Geographic projection (lat,lon)
I can see the lat lon coordinates using the "pixel coordinates" tool but my ErMapper 6.1 does not reproject the data... ANy suggestions? Sincerely M.

My ecw files are at a = pixel resolution of 0.25ft. I would like to plot at a scale of 1:4500. I did = some math and figured I would need to resample to 29 inches or a little over = 2 feet. Is there a way to have ER Mapper do the resampling - like some = wizard? I have been trying it by saving the mosaic of the original .ecw files = as an ers and resampling the ers accordingly. However I was hoping for a more automated method. Perhaps I can just enter my plot scale and a little = more information and it can do the rest. Any ideas?

You need to close ER Mapper, add the following lines to the files in the GDT_DATA folder, then restart ER Mapper. The new projection is named "L2_MEX_INEGI" with the lamcon2 projections. Add to lamcon2.dat: L2_MEX_INEGI, 0.0, 2500000, 0.0, 0.0, 1.0, -1.780235837034, 0.305432619099, 0.514872129338, 0.410152374219, 1, 0.0, 0.0, 0.0, 6378206.4 ,0.0822718542249391,294.9786982, 1 Add to project.dat: L2_MEX_INEGI ,lamcon2,1.0 ,6378206.4 ,0.0822718542249391,294.9786982 ,1 Add to projinst.dat: L2_MEX_INEGI,lamcon2,1,1,292,01_lamcon2,MEXICO,,LCC proj for Mexico from INEGI,WORLD,PUBLIC Eric Augenstein --------------------------------------------------------------- Earthstar Geographics 5330 Carroll Canyon Road Suite 206 San Diego, CA 92121 USA Email: [EMAIL PROTECTED] Web: www.es-geo.com Tel: +1 858-455-9970 Fax: +1 858-455-9971 --------------------------------------------------------------- ---------------------------------------------------------------------- Date: Tue, 26 Nov 2002 14:57:07 -0800 From: Eric Augenstein <[EMAIL PROTECTED]> Subject: Re: Resampling Reply-To: [EMAIL PROTECTED] >Jeff - > >I would like to resample my .ecw files to plot.

Set AutoVary:Page or AutoVary:Borders and you can enter the exact map scale for the plot.

Currently, it supports ECW and geotiff. The area I am working on is an island. I would like the areas of sea be 'untouched' by the hill-shade image layer. The internet map can output jepg and png (which i currently use) formats. Therefore transparency is needed. Does ECW supports it?
