Dear Margherita, what about increasing complexity and adding a true spatial database in the middle? You could use PostgreSQL as a shared database that works well with both. I think both QGIS and FileMaker would benefit a lot by having an ORDBMS to help them to manage data in a more efficient way.

[gdal-dev] How to deal with IIP image via WMS minidriver?

2015-09-03 Thread Carlo A. Bertelli (Charta s.r.l.)
Hello, is there a way -- maybe using the WMS minidriver -- to open an IIP streamed picture? The online service is well documented ( http://iipimage.sourceforge.net/documentation/) but unfortunately it shows that the protocol is not at all compliant with the WMTS or TMS or Google/SlippyMap

Thanks a lot, Roger, it worked like a charm, just fiddling a little with parameters and than run it in python. It's really magic, I struggled with this question for two days before writing to the list. I think that instead of making another script you could add it as an option to gdal_contour.py

2013-07-03 Thread Carlo A. Bertelli (Charta s.r.l.)
Hello, gdaldem makes a very good work and gdal_polygonize.py too, but the combination is not so effective. Is there a way to obtain smooth polygons representing shaded areas as it's possible with Arc? When using a dem, you get polygons for pixels. Yes you can dissolve them, but you still have

2013-05-06 Thread Carlo A. Bertelli (Charta s.r.l.)
hello, I had a fairly clean map with street codes, a very good candidate for optical character recognition, so I tried to recognize it with some of the available ocr engines and applications, just to try what if. To my surprise, ocropus (https://code.google.com/p/ocropus/) got something useful.

[gdal-dev] Erosive pyramids again

2012-02-12 Thread Carlo A. Bertelli (Charta s.r.l.)
Hello, some time ago I complained with this list, asking for a better algorithm for black and white and paletted raster maps. While you scale the image, smaller black lines become thinner and thinner, scaling to half size usually works without data loss but further size reductions result into

I don't understand the question (you didn't put any question in your message), but I tried the mif/mid files provided. The first time I got an error: Not enough CoordSys parameters specified for projection 8. (which means State plane 1983). You provided this: CoordSys Earth Projection 8, 74, 'm',

[gdal-dev] WMS overlapping tiles

2010-08-02 Thread Carlo A. Bertelli (Charta s.r.l.)
Hello, JOSM wms and the fairly simplistic Grass r.in.wms allow tile overlapping which is sometimes very useful when checking map consistency and trying to spot digitizing errors. I didn't find this option nor in the xml definition nor in gdal_translate. I imagine it could be feasible with an

Thank you very much to you, Frank, and Camp To Camp. This is a very welcome addition for file based datasources. GDAL is becoming more and more powerful, versatile, useful and ... big. Maybe you could add a -straight clause so to avoid the parser. GDAL/OGR shoud remain fast when used only as a

[gdal-dev] Stop gdalladdo eating fillets

Hallo, I have a set of very detailed bw needing an overlay. But when I run gdaladdo, no matter what option I choose, fillets are spitefully deleted. I don't know if there is a better solution, I tried to get a thicker trace on a copy of the original image, make the pyramids and rename the
