[GIS] Opening ArcGIS Desktop layer package (.lpk) file using QGIS on Mac

convertlayer-filelayer-packageqgiszip-codes

I downloaded an LPK file from the ESRI site that contains USPS defined zip codes. Because I'm working with QGIS on a Mac, I converted the file to a .zip. There's a .lyr file that opened up in the zip, but I'm not able to open that up on QGIS.

Is there a way to convert the contents of an ESRI layer package file (.lpk) into a shapefile with the associated data, and that I can open with QGIS on a Mac?

I looked into using utilities like 7-zip, but it doesn't seem to work on a Mac.

Apparently one of the .xml files in the layer package should contain a link to the actual data under the packagelocation tag, but I wasn't able to find that tag in the .xml files.

Does anyone know if that tag name might have switched?

I downloaded the layer package file from here.

From the Comments it appears that the asker solved this by unzipping the *.lpk to find a *.sdc file that was then converted to shapefile format using instructions from NCSU Libraries' Geospatial Data Formats page:

With ESRI Data and Maps 2006, a standalone "Data Distribution Application" was included that converts SDC data files directly to shapefiles. This application may be downloaded from the Geodata Server at http://gisdata.lib.ncsu.edu/esri2006/data_maps/DDA/ [needs credentials] or off-campus from here [needs authentication]. A help file is also included at this download location.

Your code tries to get the catalogPath property of the group layer containing your rasters, which doesn't exist. Instead, I would retrieve the dataSource property of the Layer, after testing that it is indeed applicable with the supports() method (group layers don't support this property).

Your code would look like this:

import arcpy
mxd=arcpy.mapping.MapDocument(r"S:\path_to_mxd.mxd")
dataframes=arcpy.mapping.ListDataFrames(mxd)
for dataframe in dataframes:
    for lyr in arcpy.mapping.ListLayers(mxd, "", dataframe):
        if lyr.supports(dataSource):
            print lyr.dataSource

See the help page for Layer properties and methods for more details.

If you want to follow @Hélène's suggestion and list all rasters in a gdb, use the arcpy.ListRasters() function. If all your rasters are in the same workspace, this would indeed be more straightforward than putting everything in an mxd to get your list.

If you don't need the symbology that is packaged with the layer, you can simply unzip/decompress the lpkx and grab the FileGeoDatabase within that contains the data.

As for the symbology, you'd need to publish the LPKX to ArcGIS Online and then download the symbology from there.

So, no easy work-arounds, but you do have access to the data itself from within the lpkx without much hassle.
