Also when they have proper Radar installed they can then see that the rain is falling in these areas, and inform the concerned citizens miles away that they could expect a flash flood. Flash floods caused by rain in isolated areas probably kills more people, since people think it is all safe then the water rises unexpectedly elsewhere. If you are going to do a job like this it is better to do it all correctly than what they have done before which is piece meal which just adds to the frustration when disasters like this occur and you cannot even go back 20 or 40 years to get a good topographical map of the areas concerned. Do it right or not at all. Yes they can prioritise populated areas, but map the lot and then later also the other departments like land use planning, Land titles, can use them. MY 2 Centavos, I do think it is a little costly, but then again looked at your electricity bill lately (2nd most expensive in Asia) ___ talk-ph mailing list talk-ph@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ph

At the moment NAMRIA has very few urban areas covered (such as Metro Manila Cebu, Iloilo). By geodata's estimate that's around 13,000 mapsheets.

Re: [talk-ph] Fwd: Planning ahead of disasters with GIS
How big an area do the data sheets cover? Maybe the budget also covers data maintenance over a set number of years? Then again, the government tends to "overbudget" on IT projects like this. :-/ On Mon, Oct 12, 2009 at 4:09 PM, maning sambale wrote: > Pucha!

Re: [talk-ph] Fwd: Planning ahead of disasters with GIS
I'm all for unifying GIS data for the whole Philippines, but before they get on another mapping spending spree, please let us know whatever happened to the geohazard mapping they initiated after the leyte landslides: http://www.newsflash.org/2004/02/pe/pe003835.htm Was it successful? Did LGUs used the data? Were lives saved because of these maps?

Incredible! it just might be a ploy to justify more government spendings :) I guess its up to us to really inform the government that OSM can really help.

Pucha! I almost fell-off my chair! "With each map sheet costing P500,000, creating a GIS base map will cost P6.5 billion." I know data creation is expensive, but is it really that much (500K per mapsheet)? -- Forwarded message -- From: r...@cp-union.com Date: Mon, Oct 12, 2009 at 3:31 PM Subject: Planning ahead of disasters with GIS To: maning sambale Sagutin natin na may available ng mga opensource tools for this and what we need are more support from the government to complete base maps ng phil.
