Starting Point: AGENCY OF MAPPING: PHNOM PENH
Enjoy – I’m quite excited to have made it even this far – if you come up with anything else then please by all means pass it along.
After much searching and many folks (Wil!) offering up data and talents there finally appears to be emerging a 3D file of Phnom Penh. Thus far the data remains un-sourced as it is an effort at bringing together information from various years and people. I’m not sure how to go about verifying it other than extensive surveying. Perhaps a project someone more GIS minded will one day undertake? A 3D model of any city is a moving target – particularly one changing as quickly as Phnom Penh. A little background on the impetuous for the project below:
Goal: To Create and distribute via the internet a free, current, digital map (and 3D model) of Phnom Penh.
Format: GIS, AutoCAD, Rhino
1) The conception of Phnom Penh as a city is heavily influenced by the image provided by the tourist maps, as they are the most readily available source of mapping information.
2) Current maps do not depict the nuances and diversity of urban space in Phnom Penh. More importantly, I have yet to find a cadastral map. I have been told that an estimated 60% of people in the city do not hold title for their property – although, again this is unverified. From what I understand this is due largely to the policies instated regarding Land Ownership After the Khmer Rouge.
3) Traditional city maps of Phnom Penh (will find an example to post) preference formal spatial structures and exclude informal communities (examples: homes/businesses) and community structures (examples: open markets). Or these spaces are mapped as ’empty’.
4) Existing maps do not adequately differentiate between spatial types. (Example: Lucky Supermarket (a Western style grocery store) and Psar Kabkor(a Khmer open market) are spatially and experientially very different but both are mapped with the same ‘market’ icon on Open Street Map – though this type of spatial differentiation is not the goal of OSM – this type of icon use can be very misleading.)
5) Mapping gives legitimacy to informal environments and challenges maps of the city which reinforce existing power structures. (Example: Boeng Kok Lake still shows up on Google Map despite being filled in displacing 4,000 families.)
