ABSTRACT:
This article will discuss a technique to convert raw or filtered laserscan-data to rasterized terrain or elevation models, by using
ESRI’s ArcGIS and Python. This programming language is supported since ArcGIS 9 and makes it possible to use the ArcGIS geo
processor’ (Rodman & Jackson, 2006). For these digital terrain models, filtered airborne laserscanning-data (ALS-data) are used,
processed with automated tools from the 3D Analyst Tools. These tools will be programmed in such a way, a minimum intervention
of the user is required. This procedure may look very comprehensive, but accessible as well. This is done to make it as transparent as
possible and to allow only the direct ESRI's ArcGIS tools to be black boxes. The proposed procedure itself will make it possible to
gain the scientist full control on the process, by using regular software and without thorough knowledge of programming. Executing
the proposed procedure will result in a set of separate TIN’s, rasters, and a mosaic of rasters.
1. INTRODUCTION
One of the most important tools in geo-science are height maps
and derived products. In different geographic subdomains, such
as archaeology (Devereux, Amable, & Crow, 2008; Gallagher
& Josephs, 2008), landscape science (Werbrouck, Van
Eetvelde, Antrop, & De Maeyer, 2009) or hydrography (Cobby,
Mason, & Davenport, 2001), these maps are widely used for a
big variety of applications. With the introduction of LiDAR
(Light Detecting and Ranging) and multibeam, scientists are
able to dispose high-resolution datasets in a very short time and
at a relatively low cost. But without further manipulations of the
data, most of the geo-scientist will not be able to gather the
information they need. That is why different transformations are
required to obtain the desired products. The biggest bottlenecks
in this process of transforming datasets in proper height maps
are loading the points and interpolate them to a predefined
raster. The first step is constrained by the amount of internal
memory of the computer. The market offers several programs
that overcome this problem, by using a direct link between the
data file and the program. Without this intermediate step of
stocking the data in a temporally database, the maximum size of
a dataset can be exponential in comparison to regular GIS
software. On one hand, commercial programs that are able to
process huge point sets are expensive. On the other hand, open
source software is rare, still in development stage or unfriendly
to use for many geo-scientists. Consequently, it would be
reasonable to use the GIS-software a geo-scientist normally has
