I'm currently working on a project in which I'm trying to assess the SkyViewFactor of a given roof using building vector data. I've already managed to build a process based on vector rasterization and the use of raster algorithms (e.g. : SAGA SkyViewFactor or GRASS r.skyview). However I'm...

I wanted to convert Raster into Point Vector in QGIS. Is it possible? QGIS have option to convert it into polygon but i didn't found any tool to convert it into point. can anyone help me? أكثر...

Bonjour, voilà je ne comprends pas pourquoi je n'obtiens pas la même surface totale d'une couche entre QGIS 2.8.1 et MAPINFO 12.5 ? :devil::taistoi: Sur un dossier où des surfaces totales doivent retomber à l'identique (une zone et son contenu), je suis embêtée pour savoir qui a bon, en...

When constructing a toolbar such in the example given at http://developers.arcgis.com/javascript/samples/toolbar_draw/ there is a slight issue when you're trying to place to first point of any drawing tool. If you are too fast (it seems to be about 2 seconds) the click won't be registered at...

I have a raster that contains values ranging from 1-180. I am looking for a way to create a new raster where if the values of a cell in the original raster is between 1-10 the new raster cell gets the value of 1, 11-20 gets the value of 2 etc... I'm sure there will be a quick and simple way to...

I'm attemping to buffer a polyline that the user has drawn on a map (Google maps and OSM map). The user specifies a distance in metres and a polygon should be drawn around the polyline representing this buffer zone. I'm currently doing this by making an AJAX call passing the Wkt string of the...

I am trying to edit an ESRI story map (just the html) so that I can integrate a jquery-ui dialog box in the webmap. I have the correct links in the head, and the correct javascript piece, but for some reason my dialog div does not seem to connect with the jquery-ui library. Is there another...
