maunaloa Posted October 7, 2011 Report Share Posted October 7, 2011 Hi ppl! I have difficult question:) There is a map collection, all maps are in ecw format, and the scale is 1:25000. I want to mosaic them with GlobalMapper to a big, but single ecw file. The problem is the frame of these maps. All maps are scanned, and they have frame, with subtitled informations, graticule etc.. If i open them in a GIS software, each map section covers some place on the neighbour sections. What i need? If possible, clip the frame from each raster and mosaic to a new one. Any idea?

3dbu Posted October 7, 2011 Report Share Posted October 7, 2011 sure man is better make and index layer of the area of the map and then can use this index for clip each map...this the fir road the second road is more easy you can make mosaic and edit the area of overlay that can be clip or eliminate in the same process of mosaic ...i hope be useful...regards Quote Link to comment Share on other sites More sharing options...
maunaloa Posted October 8, 2011 Author Report Share Posted October 8, 2011 thx mate! ...i dunno, ya feel sometimes, ya need a method, a solution, and ya thinking on very complex ways. BUT the solution is based on a simple method... That index layer thing is interesting, can you help me a bit about that indexing, etc. ? If i make a layer in arcgis, and fill with that map collections sections, i can setup, which frames will be eliminated by display the maps?

maunaloa Posted October 8, 2011 Author Report Share Posted October 8, 2011 I've tested the two ways: - once, if i mosaic the data, there are options for mosaic method: first, last, mean, blend, max, min. These are only control, which pixel will be deleted, and which will stay in the new raster. I need to mosaic with delete the overlapping parts. - second, i searched, googled, but i didn't find any info about index layer. Any idea?

Lurker Posted October 8, 2011 Report Share Posted October 8, 2011 you can make a fishnet polygon to make index layer, once its created based your image, you can filled the polygon attribute based your image properties, after that, you can crop your image and mosaic those image enjoy Quote Link to comment Share on other sites More sharing options...
maunaloa Posted November 3, 2011 Author Report Share Posted November 3, 2011 olla I've paused that batch mosaic and clip project. Now i started it again. I've created a fishnet, and now i can georeference all rasters to the fishnet. I tested the clip command, and i can't clip more than one raster with one polygon layer. The result of the command is a big raster, and the overlapping parts aren't cropped. Esri "ask carto" helped: i need arcgis 10 instead gis 9.3, and i can make raster footprint, etc. etc. I will test it. Btw i1ve tested globalmapper to make the operation, but it resulted same like Gis 93.1. sry... Quote Link to comment Share on other sites More sharing options...
Lurker Posted November 6, 2011 Report Share Posted November 6, 2011 you can use batch clip, after you separate each polygon of fishnet, but I think it will be long time job, compare if there is already a nice tool in ArcGIS 10 good luck regards, Quote Link to comment Share on other sites More sharing options...
maunaloa Posted November 6, 2011 Author Report Share Posted November 6, 2011 I like arcgis, but ver. 10 isn't good for this mega operation. I thougt, i will mosaic all my map sections with global mapper to one big ecw file. I've made an other big county map, global mapper worked around 10-15 hours, without any problem. I thought i will ask on the globalmapper forum. Mike, the magician gave me a tip: script! I will test it, and i will post the results!

arcsump Posted July 16, 2012 Report Share Posted July 16, 2012 sorry for butting, but is ECW one of the supported ERDAS formats? the compressed wavelets? Quote Link to comment Share on other sites More sharing options...
