changes to Map-A-Planet are nothing short of catastrophic
Ouch But keep the comments coming - we are listening and if possible we can try to figure out how to roll some changes in. We imagine the original MAP will stick around as long as the server stays healthy.
For some long-time MAP users it is going to be hard to transition to MAP2. We had to make some compromises on the interface to support more robust features. Remember, the over-arching goal for both MAP and MAP2 is to make science-ready data available for download. The fact that the almost 10 year old (second version interface) for MAP is so beloved was a little bit of a shock for me. Hats off to the original USGS designers (who are no longer with us - no they are not dead).
For MAP2 our goals were to:- Allow the ability to add new data sets in hours. The hardest part here is making sure the documentation (metadata) is available and references are in place. We will always strive to have each base well describe (some bases are still a work in progress). Do have a good base and documentation, we will add it.
- Support much larger file creation and downloads. MAP has a 2GB limit and MAP2 has a soft 20GB recommended limit. This is a limitation of the MAP engine which can't make files larger than 2 GB. MAP2 uses ISIS3 which has no filesize limit. The 20GB recommended creation size is to just help with download volumes. Fortunately, we are also working on a moving the created downloads to a faster network.
- Support all the map projections available in ISIS 3 (including Orthographic, Transverse Mercator, Lambert, Polar Stereographic, etc.)
- Nearly all MAP2 files are be available for download as one file (ISIS cube and/or GeoTiff/GeoJpeg2000) instead of always stuck behind an ordering web interface.
- All output formats are "mapping" ready with proper geospatial headers which include the map projection and cellsize. Even the Jpeg and PNG files have GIS projection auxiliary files. Worldfiles just don't cut it anymore.
- Because we are using the more modern ISIS 3 and GDAL and our cluster for processing, we can more easily implement new functionality (e.g. hillshades, slope maps, colorizing, blending, filters, even perhaps rendered 3D fly-overs, etc.)
In regards the login system, we know it can be an annoyance. But besides it allowing us to better help users and tally popular use cases, it will eventually allow you to recall previous settings and share settings with others. But feel free to share one login/password with a group or classroom. Other benefits include allowing us to eventually support "domain-specific" jobs for users (e.g. recommended settings for GIS apps or Matlab users) and the same login will also get you access to
POW (our single image processing service which runs on our cluster for you, also helps to learn ISIS3). We have considered "guest" accounts for pipeline and anonymous usage but users will still need to provide an email address.
I hope this helps explain some of the decisions we made. Again, feel free to post comments, especially if you find issues or have a data/capability wish list.
If you are missing the interactive part of MAP, then this
post might help. Open up the WMS layers in one of a dozen+ applications or create your own OpenLayers map to see the glorious 500GB Kaguya Terrain Camera Ortho mosaic in full-res (~7m/p). Process some images in POW and then add them on top of a downloaded MAP2 base or live planetary WMS layer in QGIS! Pretty cool.
