First test prints from Ultimaker 2+. Atauro island – Timor Leste. Produced from 30m SRTM data.
Sentinel-2 is a very new satellite launched last year by the European Space Agency (ESA). Sentinel 2 data has become freely accessible through the Amazon Web Server Site. It’s high spatial (10 meters) and temporal resolution (10 days) will make it a great extra tool for high resolution mapping.
Below is a series of example images from:
Darwin Northern Australia as a Natural colour composite and using the Infra-red band.
South East Sulawesi Gold mining district as a Natural colour composite and using the Infra-red band.
And finally from Kupang in West Timor (Indonesia) a Natural colour composite and using the Infra-red band.
You can see a comparison of the image bands here:
Below is a quick video showing how to download Sentinel imagery and load it into SAGA:
The import function in the free open source SAGA-GIS software makes viewing Landsat data on your own desktop a simple one step process. There is no other tool, free or commercial providing an easier way to import and visualise Landsat data.
The SAGA tool combines three separate functions into one easy dialog box.
A couple of Photos from a recent demonstration for the Tiwi Land Council at CSIRO Darwin. Infrared interactivity allows the fire spread model to be initiated via cigarette lights.
The SAGA GIS travel time tools were created to join together and automate a number of processing steps in order to simplify service access modelling. The purpose of these tools is to create a simple open source way of calculating travel time to services to facilitate rapid testing of multiple travel scenarios.
Defining Remoteness from Health Care: Integrated Research on Accessing Emergency Maternal Care in Indonesia. Bronwyn A Myers, Rohan P Fisher, Nelson Nelson, Suzanne Belton.
Complex interactions between geographic and socio-cultural factors affect access to, and remoteness from, health care but research on this topic rarely integrates spatial and social sciences. In this study, modeling of travel time was integrated with social science research to refine our understanding of remoteness from health care.
A new update version of SAGA has been released fixing some of the landsat display bugs from the previous 2.2 version. Download it here:
