Install Android on Odroid-U3 (SD-Card, Linux)

Some words on how to install Android on your Odroid-U3 using Linux:

  • Download the Image from http://dn.odroid.com/4412/Android/
  • Extract the ZIP-File with your GUI-ZIP-Tool or in Command-Line
  • Prepare the Micro-SD (USB-Card Reader with your SD)
    • Clear your SD with dd first: dd if=/dev/zero of=/dev/sdX bs=4M
      (Depending on the size of your SD, this action can take a lot of time…)
    • Now we flash the image on the SD-Card: sudo dd if=image.img of=/dev/sdX bs=4M
    • To safely remove the SD: sync
  • Now we insert the SD into our Odroid-U3 and first boot will proceed – and it will take some minutes (with black screen) !!! (Anyways At the first booting, the self-installing will take about 1~2 minutes. While installation, the blue LED is blinking and fan is running. The blue-LED will turn off after installation. Turn on again and enjoy.)

Python ArcGIS 10 – list all FeatureClasses in SDE-FeatureDataset (to txt-File)

If you want to list  and write to a txt-File all featureClasses (in a FetaureDataset) stored in SDE/Oracle, it is done with a few line Python.

import arcpy
from arcpy import env
import os

# Set the workspace for the ListFeatureClass function
#
env.workspace = "Database Connections/VECTOR.arcsde01.sde/FEATURE_DATASET"

# Use the ListFeatureClasses function to return a list of 
#  all shapefiles.
#
fcList = arcpy.ListFeatureClasses()

print str(fcList)

# setting up output-file and write to file
file = open("sdelayers.txt", "w")
file.write(str(fcList))
file.close()

Odroid-U3 XuBuntu – no image wrong HDMI-Setting. Reset HDMI-settings

If you don’t get an image via HDMI on your TFT/TV, sometimes it’s because of a wrong setting… and if you can’t connect to your Odroid with SSH (to run odroid-config), you have got a problem :-( but just a small one.

Put the SD in a Card-Reader and connect it to a Linux-PC.

The first partition, a fat partition will have a file named boot-auto.scr copy it to boot.scr (replace the old boot.scr there)

odroid_bootscr

Now your little gadget should boot with an image on your screen :-)

Use BaseMap-Austria (basemap.at) with QGIS 2.x and ArcGIS 10.2.x

The Austrian  govermental geodata-departments offer a free Basemap for Austria – Basemap.at (http://basemap.at/) – similar to GoogleMaps or OSM, based on official governmental data.

You can access this map via QGIS too – add a WMS/WMTS-Layer and use the following URL

http://www.basemap.at/wmts/1.0.0/WMTSCapabilities.xml

basemapATQGIS

… for the best rendering-quality (no distortions) choose Google’s Pseudo Mercator as Project(Display)-CRS: EPSG 3857 (in QGIS 2.x: Settings – Project properties)
