Terror in the Mid-East: It’s never been worse

when international development goes wrong …

Freewheel Burning

TerrorWe are entering into one of the most chaotic chapters of modern history, though the geographic space of this chaos is smaller than it has ever been. While most countries are experiencing less terror, Mid-Eastern terrorist have never been busier or more successful.

I downloaded data from the Global Terrorism Database, which comprises more then 125,000 individual acts of terror and found that, since 2010, the number of weekly terror events when from somewhere around 10 to more than 40, and the trend doesn’t look like it’s ending anytime soon.

Moreover, while terror events are becoming more frequent, they are becoming more and more unpredictable.

While the world was shocked over Charlie Hebdoe, the troubling scale up in the number of terror events seems to have mostly gone unnoticed. Terrorists strike Islamic countries far more than they do France, and kill more than just cartoonists and policemen.

It is…

Albuquerque Live Bus Tracker

semoga cepat menular ke kota-kota di Indonesia …

Architecture and Planning

The City of Albuquerque has put out a lot of good data and they have done so in several different formats. There is one data set that I love and despise at the same time – the Real Time Bus data. I love it because I think it is an excellent example of open data. It is extremely useful as it is updated every minute. I despise it because it is in KML. I will give the City the benefit of the doubt and assume they have done this because their software for tracking the buses uses KML by default so it was an easy choice – just spit out what we already have.

As a developer, KML is worthless to me. I want a stream of data in JSON or CSV. I have struggled with what to do for some time now – ignore the bus data or…

Build large maps with OpenStreetMap

buat yang hobi bermain dengan OpenStreetMap …

Phil Mike Jones

This is just a quick post to remind me to produce a full post later when I have more time.

It’s surprisingly difficult to produce street maps in GIS for paper sizes bigger than about A2. Using QGIS for example, even if things look good in the print composer the resulting image often doesn’t have a background that extends to other layers.

The solution is to use Atlas convergence. With OpenStreetMap as a background, create your map as normal in the print composer until it looks right. Then use the Atlas composer to make sure enough tiles are downloaded and composited to cover your other layers.

You can specify which layer you want to use as the extent of your map, and you can then add a margin (by default 10%) to make sure the background extends far enough around your extent layer.

Hey, presto. Big maps.

Toronto 3d Open Data

kita tunggu kota di Indonesia …

Owen Powell


The City of Toronto has created a fantastic 3d city model and recently released it as open data. This is probably a bit more of a simpler use of the data than they had in mind, but you could do a lot, especially when combining it with some of their other datasets. Ideas, anyone?

I used FME to process the GIS data and Blender to render it. This render consists of a mix of detailed ESRI multipatch features and low-poly extruded building footprints to keep the file sizes down. In FME I filtered the multipatch models on height (taken from the BoundsExtractor) to extract features more than 200m. I then filtered the shapefile building footprints to find all less than 200m, and extruded them (from an attribute in the data) and wrote out to an OBJ file.

New Book, “Python Scripting for ArcGIS,” Now Available

eits … tadinya saya kira ini bukunya Erick Pimpler …

GIS and Science

Python Scripting for ArcGIS is a guide for experienced users of ArcGIS Desktop to get started with Python scripting without needing previous programming experience. Python Scripting for ArcGIS is a guide for experienced users of ArcGIS Desktop to get started with Python scripting without needing previous programming experience.

Python Scripting for ArcGISis a guide to help experienced users of ArcGIS for Desktop get started with Python scripting. The book teaches users how to write Python code that works with spatial data to automate geoprocessing tasks in ArcGIS. Experience with other scripting or programming languages is helpful but not required.

Key topics in this book include Python language fundamentals, exploring and manipulating spatial data, working with geometries and rasters, map scripting, debugging and error handling, creating functions and classes, and creating and sharing script tools. Python Scripting for ArcGIS contains 14 chapters with corresponding online data and exercises available on the Esri Press book resource page at esripress.esri.com/bookresources.

Load GeoJSON in ArcMap

buat yang ngga mau pake QGIS … eh?

Architecture and Planning

It came up on Twitter that you cannot edit GeoJSON in ArcMap. That gave me the idea to try and write a plugin that allows just that. This post will layout a procedure for editing GeoJSON in ArcMap. The final code solution needs work, but it is a good start.

Reading GeoJSON in ArcMap

I grabbed a text file from my Github and saved it to my desktop. This is not the best example, but it was good enough to test the process. I started by reading the file in to ArcMap. The code reads in the file and converts it to JSON. It then iterates through the features, grabbing the coordinates and putting them in to an array.  Lastly, it writes it to a default geodatabase.

import arcpy
from arcpy import env
import json
for x in data[“features”]:

You will have a map like…

Geovisualization: A Newer GIS Technology for Implementation Research in Health

buat mahasiswa GIS yang sedang mencari topik untuk skripsi, tesis atau desertasi, silahkan follow Journal of GIS dari SCIRP

Use of GIS in public health is currently limited to tracking immunizations, disease surveillance, and establishing new service areas. The potential of GIS to improve planning, implementation and monitoring of programs and to inform policymaking processes for universal access to healthcare is grossly underutilized. Major reasons for restricted use are paid access to GIS software and difficult interpretation for non-GIS professionals. WebGIS technologies present an opportunity for non-GIS public health professionals to present complex data and findings in simpler manner. Conventional GIS methods and Geovisualization are compared and contrasted in this paper using data from the MATIND project in the Gujarat state of India. In-depth literature…

Making Maps of the World Using GIS Resources

artikel yang bagus dari ProxymityOne, barangkali ada yang ingin mencoba?

Decision-Making Information Resources & Solutions

Visualize world geographic-demographic-economic characteristics using tools resources described in this section. Zoom-in to any region of the world and examine political/statistical geography. This section provides illustrative views of the world by country, and drill-down geography, developed using the World GIS project. Install the World GIS project on your computer using the steps described here. Create alternative thematic pattern views, label and view selected geography to meet your needs, add your own data …

Geographic Information Systems (GIS) resources enable you to examine how countries, their states/provinces and lower level geography relate to one another. By integrating subject matter data, such as demographics, thematic maps can be developed that provide insights into patterns.

North America by State/Province
The World GIS project integrates multi-sourced geographic data. The following view shows portions of North America by integrating Census Bureau sourced TIGER/Line shapefiles, Canada and Mexico by state/province shapefiles and OpenStreetMaps
