Data used in workshop (same datasets as used in previous workshops on this website):

I. Viewshed Analysis 2009

nico — Sat, 14 Mar 2009 22:52:17 +0000

This exercise will demonstrate two types of viewshed analysis.The first is a single site Viewshed, and the second is a general measure of visibility or exposure.

To begin with, please download and unzip the following dataset: 2009_View_Cost.zip (2mb).
Place the data in a directory under C:\ (not in My Documents) so that the path is simple and has no spaces. You might use
C:\gis_data\

II. Cost-Distance 2009

iTrek Z1 GPS datalogger precision test

nico — Sun, 06 Apr 2008 20:58:49 +0000

The iTrek Z1 datalogger GPS with a solar panel is based on the MTK chipset produced beginning in Q1 2007. I brought this GPS data logger, along with three other GPS units, on an ethnoarchaeological research project in Peru in 2007 where we travelled with a traditional salt-bearing caravan for 14 days, and I gathered 9 days of data logging with the iTrek Z1. I conducted this test to evaluate the precision of the GPS in the southern hemiphere where there is no WAAS.

Citing and Permission for use of ASTER data (and others from LP DAAC)

Tue, 29 Jan 2008 18:37:02 +0000

I just got a definitive email response on how to cite ASTER data (or other data from the same source), and that there are no restrictions on their use. I am publishing a paper in ESRI's ArcUser, whose the editor also got this email, so ESRI should now be aware (if they weren't before), that these data are acceptable for publication (you don't have to only use ESRI's data).

Thanks to Janice Wilson for clarifying this!

The Effects of the Curvature of the Earth, the Refraction of Light in Air, and Fuzzy Viewsheds in ArcGIS 9.2

Mon, 28 Jan 2008 02:24:30 +0000

In making viewshed calculations, the earth's curve and the refraction of light in air have an impact (albeit minor) on lines of sight. I this post, I provide some links describing how Arc calculates both variables. I would love to find out how to recalculate the "refractivity coefficient" of 0.13 to other situations. I also put a plug in for fuzzy viewsheds, a drastic improvement that was first suggested 15 years ago, to be mostly ignored in practice until very recently.

Finding the right transformation when re-projecting data in ArcGIS 9.2

Thu, 17 Jan 2008 05:45:41 +0000

So you're using the Project Tool to re-projecting a map into a new projection.

Before you can start the process, you have to choose from the many transformations. The attached file (World Projections.xls) lists where in the world each projection transformation should be used.

For example, if your map is in PSAD56, and you want to project it to WGS84, the Project Tool will ask you which transformation you want. Checking the lists for Bolivia, I find: PSAD_1956_To_WGS_1984_2

Using recreational-grade GPS units for fieldwork

nico — Sun, 15 Apr 2007 00:25:48 +0000

GPS technology has greatly simplified the process of locating sites and features on the landscape and mapping positions, linear features, and areas. There are two main groups of GPS units used by field scientists: "recreational" and "mapping" grade GPS units. This post is about using Recreational GPS units for fieldwork in 2006.

Importing ASTER (14DMO) DEM and Imagery into ArcGIS 9

nico — Thu, 15 Mar 2007 15:12:56 +0000

Steps to using ASTER14DMO DEM and Imagery data in ArcGIS 9.1 or 9.2

The ASTER14DMO format file contains 15 TIF files. These include 14 bands of imagery (V1-3n and 3b, S4-S9, T10-T14), and a DEM file. If you have an HDF file see this posting first. DEM 1. Open the TIF file and right-click layer > Data… > Export Data… choose Format: GRID 2. Give it a legal filename for GRIDs (short filename, no spaces or weird characters) 3.
