How to load a DLG file into QGIS?












2















I downloaded hypsography (topo lines) in DLG (Digital Line Graph) format. The file came from OGRIP, although it originally came from USGS. According to Wikipedia, DLG files are




topologically structured for use in mapping and geographic information system (GIS) applications.




However, when I try to load the .dlg file into QGIS, I get an error message:




Invalid Data Source: C:/Users/.../cl303ohy.dlg is not a valid or recognized data source.




Searching for how to load a DLG file into QGIS doesn't yield any helpful results. Apparently 'dlg' is used in the python coding for creating or loading a plugin, so all the search results discuss plugins.



TL/DR:



How can I use a DLG file in QGIS?






qgis file-formats usgs

          DLG (Digital Line Graph) format is not a valid OGR data source (it can be corroborated in OSGeo4W shell with ogrinfo --formats command). So, you need a data converter for DLG vector files. This coverter can be downloaded from here: https://esri.box.com/v/sdtsdlg2shp .



          At following image, you can observe its GUI.

          Into unziped folder, there is User’s Manual for DLG2SHP.

                    ASUS Zenbook UX433/UX333 — Configure Touchpad-embedded numpad on Linux

                    Image
                    0 1 I have an ASUS Zenbook UX433,on which ASUS decided to innovate by embedding a Numpad inside the touchpad (see picture 1). Toggling between classic touchpad mode and numpad (also turns the touchpad LEDs on) can be done through the golden button in the top-right corner of the touchpad. However, on my Manjaro arch Linux config, this behavior does not work by default and I can only use the touchpad, no numpad. Has anyone been able to configure the numpad to work on Linux, or have any idea how this could be achieved? EDIT1: I have had a look at the official Windows drivers for the UX433FA TouchPad, but was not able to make anything of it. I tried installing them on Linux using tools like NDISWrapper, but they do not detect the TouchPad/Numpad hardware, and my understanding of drivers is too limited.
