AcrGIS Server vs. Mapserver vs. Geoserver

November 7th, 2009 No Comments »

Hello,

here is a very interesting slide show about the benchmark between these mapping servers. Unfortunately ESRI declined to take part in this competition.

WMS Performance Shootout 2009View more presentations from Jeff McKenna.

Seems to me as if Mapserver and Geoserver are nearly the same for vector data and shape files. According to raster the Mapserver FCGI is better than the Geoserver . Geoserver cannot handel BigTIFF so they had to make 2Gb tiles.

Hope you liked it!


Setup for Spatial-Data-Infrastructure

November 7th, 2009 No Comments »

Building a Spatial Data Infrastructure SDI for Web services and Web Mapping Applications
from Scratch – My Link Collection v 1.0

There are several Ways to setup a SDI with OGC Webservises! In this post I would like to introduce my approach to reach a complete free SDI with Linux, Geoserver and PostgreSQL.

The setup will be a Linux OS in VirtualBox 3.x:

 

Linux in VM

Select one of the following Linux Distributions

CentOS (Redhead)

http://www.centos.org/

Download: http://mirror.centos.org/centos/5/isos/

Good as server system but short release rotation

 

Fedora11

http://fedoraproject.org/en/get-fedora

Desktop system with less command-line input – also shot release rotation

 

OpenSolaris

http://hub.opensolaris.org/bin/view/Main/downloads

Server-system. Big advantage is the connection to Java(Script) since OpenSolaris is from Sun

 

Debian

http://www.debian.org/

Long lifetime

 

Java Runtime Environment 6

Setup JRE

Sun JRE 6 Java Environment 6 http://java.sun.com/javase/downloads/index.jsp
or download as package in any package manager

Geoserver 2.0 does not require JDK anymore, just use the JRE

Apache2 – Tomcat

??? Need help at this step J

 

PHP 5

aptitude install php5

or

use yum / yumex to install php

CentOS 5.4 guest on Win7 host with VirtualBox

November 6th, 2009 No Comments »

Thanks to this blog and the way to lower the CPU usage your guest system is producing.

My poor confguration is a AMD 3000xp+ with 2Gb Ram and with this simple fix its working perfect. VBox drops down to <15% CPU

Here is the line for /boot/grub/menu.lst

su

***********

sudo gedit /boot/grub/menu.lst

kernel /vmlinuz-2.6.18-164.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet divider=10

restart

Have fun!
