Zulu 7 on DVD set now available!

Posted by Maurizio on 03 Mar 2005 | Tagged as: Satellite Imagery

MadMappers has now available on DVDs the African collection of Zulu 7 False colour mosaics, over 30Gb of highly compressed satellite images at a resolution of just over 14m/pixel from Landsat 7.
We have chosen False Colour because of the high contrast and crispiness of the images, which allows finer features to be identified.

Price for each DVDs is R150 (US$25). For the set of available DVDs, postage charges (anywhere in the world) will not be applicable!
Check the mapsets on CD section for more details

MadMappers is one month old

Posted by Maurizio on 03 Mar 2005 | Tagged as: Uncategorized

February has been a long/short month.
Short  for the number of days in the calendar but mostly because many of the targets were not achieved. I guess we were over-ambitious: time, time, time.
Long, because as our monthly traffic cap shrunk very quickly and was exceeded extremely quickly: we would have liked this February to be only 10 days long!
In truth we had never hoped to have so much traffic, there are more MadMappers out there than expected. Very surprising to us was the area distribution of the traffic, truly international, with only 26% share for South Africa. All Continents were well represented except Asia.

We have succeeded in finding a bandwidth sponsor in North America and we are confident to have a reasonable amount of downloadable maps shortly. Data is on its way to the USA and should be loaded on the server any time soon.

We have also received some interesting data contributions from academic institutions. Data will require extensive processing but will enable MadMappers.com to offer some unique products not available anywhere else.

You might have noticed that search for Vector data returns “no such data available”. This is does not mean that that data does not exists, just that it has to be entered in the MM archive. Before doing that we have to find the most practical way to list it, possibly in graphic form, and most importantly it should be presented in a standard projection and format suitable for everyone to fulfil the aim GIS data accessible to all.
If you have any particular requirement enquire with us

Finally a big thanks to all the guys who have been helping: without you it would not have been possible.

African Index Maps for OziExplorer added

Posted by Maurizio on 25 Feb 2005 | Tagged as: GIS software, Maps

Behind any map archive, no matter how small it is, there should be a set of index maps: overview country maps and national map-list indices. By the use of index maps the required correct map will be identified and located in a matter of seconds.
If you are an OziExplorer user you are lucky, the index map system is fantastic.
In the Raster Maps - Africa Index Map section you will find overview maps for every African country in ozf2 format. Store them in the Index Maps folder of your OziExplorer program directory and you will never loose a map again.
If you are not an OziExplorer user do not despair: tell us which program you use and which image format you prefer and it will be added. In the meantime you’ll be able to use the index maps in the free Trial version of Oziexplorer.

We have included 2 national maplist maps: Namibia and South Africa. With them it is possible to identify the name of any 50k map in these countries. If you have maplists of other countries please send them to us and they will be included in the National Maplist section.

South African 50k on DVD set now available!

Posted by Maurizio on 23 Feb 2005 | Tagged as: Maps

Is it possible to compile 30Gbs of digital maps into a simple, easy to use set?
2 DVDs is the result we are proud of. By virtue of this achievement MadMappers is now able to offer the SA 50k mapset at a cost lower than anyone had hoped for and ready to use with OziExplorer and Global Mapper: all it is required is to place the DVD into the DVD drive and load the maps. As simple as that.
Price for the 2 DVDs set containing over 2000 maps is R550 (US$90). DVDs are also available separately. Check the mapsets on CD section for more details.

Unfortunately (or … fortunately?) after only 15 days we have exceeded our traffic threshold for the month. Nevertheless, we are making available some free sample maps of the SA 50k set for those who are not familiar with them:

2528CC Centurion
2628AA Johannesburg
3318CD Cape Town
3418AB&AD Cape Peninsula

Keep watching: more sets are to be released soon.

Maps download system tests

Posted by Maurizio on 10 Feb 2005 | Tagged as: Maps

We are conducting system tests. Please keep it in mind if something unexpected occurs.
3 maps of South Africa scale 1:250.000 are currently available for free download:

3318 Cape Town
3319 Worcester
3320 Ladismith

You will notice that pages relative to these 3 maps differ from all others map pages not yet available for download, in that a grey “download” button is now present. Note that maps which are not available for download no longer have the “download inactive” button. This note was removed to avoid the impression that certain maps in archive were about to become available for download without author’s consent.
Once unzipped the above mentioned maps are ready-to-use and calibrated for  OziExplorer and Global Mapper (see GIS Tools” section). If you wish to use in other GIS software please enquire with us.
After you have completed downloading please send us a feedback mentioning:

- name of downloaded file
- time and duration of download
- average download rate (if available)
- type of connection
- GIS software you use (optional)
- any other comment

Once tests have been successfully completed the set South Africa scale 1:250.000 will become available for free download.
