File Geodatabase in QGIS 2.4 Note: Use Directory rather than File Once the file geodatbase is loaded save the shapefile

I've worked with LEHD data before, including in a GIS context so I can probably clear up some of the confusion. First off, S000 does not represent a point, it represents an attribute. Secondly, I can tell that user26056 is working with Origin-Destination data because the GEOID's in the w_geocode are repeating and the S000 usually shows a bunch of 1's for ...

gdal_translate -of GTiff C:\temp\input\a.img C:\temp\output\a.tif and the batch option GDAL_translate: converting ESRI GRID to Geotiff in batch '-of GTiff' this part is probably not even required as this is the default but will do no harm.

Exporting DGN to DXF and then using ogr2osm seems to do it.

There are two things in that zip file: the "raw" raster data koppen_ics a layer file The layer file is just a pointer to the original data, with additional information about symbology (in this case, providing short text names for the various climate zones). Layer files are useful for saving a set of layers and symbology, but they can't be used if the ...

From a cartographic point of view, it is commonly assumed that the human perception of a line position is around 0.3 mm. For a given map scale of 1:20,000 or smaller, the USGS’ NMAS has established that 90% of all the points tested must fall within 1/50 of an inch (0.5 mm) (as measured on the map) to their known positions on the planet (see here). This can ...

Well, before you convert the database, you could run the Domain to Table geoprocessing tool http://resources.arcgis.com/en/help/main/10.1/index.html#/Domain_To_Table/001700000022000000/ which should convert a domain to a stand-alone table that you could put in the database. Then, you should be able to just convert the database, including stand-alone tables ...

One option that may be a bit faster (less clicks) or you could call from a script would be to use ogr2ogr command (using OSGeo4wShell (which comes with installation of QGIS)). ogr2ogr -f "ESRI Shapefile" C:/Temp/Shps C:/Temp/test.gdb If you want to export out a subset you may use the same command above but at the end list out the table name(s) (e.g. ...

This is a common issue, translating between mapinfo rasters to arc/Q can lead to positional errors. Converting using a tab-to-tfw tool will give mixed results but usually the rasters will be about 20-30m off. I would recommend either opening them in Arcmap (arc can read the georeferencing information in the tab file) and saving out a copy from Arcmap, or to ...

The point feature is a bit more straight forward once you have your table in excel (with your X and Y columns), save it out as a .csv and you may use the Make XY Event Layer tool to convert to event layer and then use Feature Class to Feature Class tool to convert to shapefile. The polyline and polygon are not as straight forward, you will have to build a ...

You do not explain what kind of data you have, but if it is point data you should be able to use QGIS to do point on polygon analysis. Here is a link to a article about this: http://maps.cga.harvard.edu/qgis/wkshop/pt_in_pgn.php BTW - Census block data are stored as vector polygons, so you should not need to transform your data to raster

There's another page on the GeoScience Australia website at http://www.ga.gov.au/scientific-topics/positioning-navigation/geodesy/geodetic-techniques/calculation-methods#heading-4 which contains a link to an Excel file. If you download this file, then un-hide rows 8-39, you may be able to unpick their formula and apply it in your app.

What I am doing in such cases is basically exporting every layer separately. Then import them all to any gis software. If you have auto cad map, it can export shp-s, for example, keeping layers in separate files. Then you also have to style every layer properly in gis. If you don't have auto cad MAP, you can save each layer to dxf, and import that to esri. ...

The transformation you want should be possible with GDAL cs2cs and a local transverse mercator projection. You can download GDAL from http://www.gisinternals.com/sdk/, but it is also availble for Linux and Mac OSX. It works in a terminal window. The unusual axis order was introduced here: ...

Technically yes, it is possible. However there are no packaged tools with SpatialNET to do so, so if you were to do it (which I would advise against in the strongest terms) the method would be to build the data in ArcGIS and then bulk-load it to the Oracle Spatial back-end of the SpatialNET instance. (There is also a Python API that you could use to build a ...
