HI, one could probably write a full chapter on this question, but here's a quick and short opinion:
> - Would you recommend using SVG for Geographical layering and > mapping systems? SVG is a format/language for graphical output. It is NOT a data format for storing geograpical data, it lacks things like indexing, topology, etc. for that. Therefore the answer is NO if you mean using SVG to store and edit your data in, but definitly YES if you mean to output the GIS maps with it. > - Is there a tool that would allow one to convert the JPEG > maps to SVG Graphics or how would one convert the JPEG or a > simple graphic file such as GIF, JPG, BMP formats to SVG images? The formats you mention are raster formats. SVG is a vector format. Converting raster to vector involves vectorizing or lin-following oand similar techniques. There are many software solutions for that. But I am not sure why you'd want to do that... Typically GIS data is either vector (eg. line/point/polygon objects) or in raster (eg. satellite images, DTMs), for good reasons, and should usually be kept in their respective domains. What you seem to mean is have JPEG as the map output and then convert that to SVG. That's illogical. You'd use data stored in GIS formats and then output the maps directly to SVG , or if your GIS software cant do that, to some other VECTOR format and convert that to SVG. > - Further more if you could kindly recommend a GIS software > capability to use SVG for GIS mapping purposes? See first answer: Some GIS systems can use SVG for their OUTPUT (the ones I know of: ArcGIS, Geomedia and for most others I think there are native or 3rd party solutions). Nowadays with OGC and other Open Standards you or not so much stuck to 1 vendor only, you can mix and/or use open sourse solutions. hope it helps, -- Barend Köbben International Institute for Geo-information Sciences and Earth Observation (ITC) PO Box 6, 7500AA Enschede (The Netherlands) ph: +31 (0)53 4874253; fax: +31 (0)53 4874335 ------------------------ Yahoo!
