Semi-Automatic Extraction of DSM from ASTER Imagery

E-mail Print PDF

In the link below, you can find the research paper which I wrote to finish my study in Geomatics Engineering, back in 2003. Please note that the paper is in Bahasa Indonesia.

Pembuatan Model Permukaan Digital dari Sumber Citra Aster Secara Semi Otomatis
(
Semi-Automatic Extraction of Digital Surface Model from ASTER Imagery)

DEM derived from ASTER


Abstract

The development of photogrammetry techniques towards to digital systems is moving quickly along with the rapid advancement of computer technology. Similarly, the development of remote sensing technology provides many new innovations in relation to the mapping activities. One of them is marked by the launch of the satellite sensor ASTER EOS-AM1/Terra which has a special ability which is sensing the same place from two imaging positions within a single orbital path, to acquire stereo image pairs. From the stereo image pair, a three-dimensional model of the imaged surface area can be formed.

RF Propagation Modeling using RadioMobile

E-mail Print PDF

Last week I searched Google for RF propagation modeling software to support my then-upcoming presentation to a prospective client. My intention was to compare the modeling result derived from SRTM DEM and the one derived from IFSAR DEM. I knew for sure that IFSAR will yield superior detail due to its denser posting space, however, I wanted to prove it by seeing the actual modeling result.

I tried several software, ranging from the very popular ones such as Global Mapper, ArcGIS with Spatial Analyst, to obscure ones such as Radio Mobile, Terrain Analysis Package (TAP) version 6, and online prediction tool such as CRC-COVWEB site.

NEXTMap Indonesia Overview

E-mail Print PDF

The latest assignment that I got from my employer is to support the sales of company's products in Indonesia. It is a bold jump from my previous duties in Production and Engineering. Therefore, through this website, I'd like to provide a short introduction of NEXTMap Indonesia. If you have any inquiries regarding NEXTMap Indonesia, please contact me at This e-mail address is being protected from spambots. You need JavaScript enabled to view it . Thank you.


NEXTMap Indonesia


NEXTMap Indonesia Datasets – Affordable and Available

NEXTMap Indonesia is a national mapping program which utilizes Intermap's IFSAR technology which enables Indonesian commercial enterprises and government agencies to quickly and affordably meet their precision geospatial needs.

The unprecedented and highly successful NEXTMap® 3D digital mapping program offers some of the most uniform and precise wide-area digital surface models (DSMs) and  orthorectified radar images (ORIs) currently available. In addition, our superior DSMs and ORIs are:

  • Commercially available and current
  • Easily accessible, affordable, and high-resolution

Donating CPU Power to Humanity

E-mail Print PDF

For you who have never heard about Folding@Home, it's a scientific project using distributed computing concept, started by Vijay Pande, a researcher at Wisconsin University. The purpose of this project is “to understand protein folding, misfolding, and related diseases”. Basically, you will need to install a client software that will pull some data to be worked on (called work-units) from a server, and starts molecular-dynamics simulation on your machine. Once the work-unit is completed, the resulting data will be sent back to the server. The processed data will then be used by the researchers.

Protein Molecule  Model

The list of scientific papers using data from Folding@Home can be found in this link in Wikipedia. You don't have to worry that the processing will interfere your real work, because the engine will work as a low priority task which yields CPU time when the higher priority tasks needs it, therefore your main programs that runs in the foreground will not be affected at all.

About Me

E-mail Print PDF

my portraitMy name is Daniel Adi Nugroho. I am a Geomatics Engineer who specializes in GIS and Remote Sensing, but has myriads of interests in many other subjects, ranging from history, photography, sociology, and personal finance, to space exploration, amateur radio, and artificial intelligence.

Music, photographs, movies, and poems, drives my feeling up and down with vibrant thrills, but the debate of the politicians and their ilk left me exhausted beyond relief. I currently live in Cibinong, West Java, Indonesia, which is about 35 kilometers away from the core of our crowded Jakarta metropolis, and that means two hours of commute everyday. That is fun.

It is my hope that you enjoy this site and find it useful for both your everyday lives and professional services. You can connect with me either using LinkedIn or Facebook.
