Re: [gdal-dev] GDAL 1.8.0 misreads images with Type=Float32 as Type=Byte

Even, Thanks for pointing out that this GDAL 1.8.0 bug was fixed 6 months ago. Unfortunately, GDAL 1.8.1 has not been released, no plans have been announced for the release of GDAL 1.8.1. The predicament is that GDAL 1.8.0 must be used to use gdallocationinfo, but GDAL 1.7.3 (and not GDAL 1.8.0)

Terima kasih, che' Himly! This is indeed a complex situation! Here's to hoping that support for these Hotine projections comes to PROJ/GDAL/OGR soon! Howard -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Michigan-GeoRef-Michigan-Oblique-Mercator-EPSG-3078-tp6517423p651

Thank you for the suggestions, Steve. The projection parameters for the list you derived are pretty much the same as the PROJ4 format of EPSG:3078, with the exception of the display unit (m vs ft) and the datum (NAD27 vs NAD83). I've tried most of them (but not the NAD27 versions), and I've als

I'm not sure how this works in gdal/ogr, but proj library uses the tag before the ":" as the name of a file containing the projection data. gdal/ogr may use an different database of projection information. Anyway, the following show these projection definitions: $ grep "Michigan GeoRef" /usr/s

All, I was wondering if there has been any progress in addressing the various problems associated with correctly projecting to and from Michigan Oblique Mercator (EPSG:3078 and its brethren), as brought up in tickets 2475, 3038, and 3311, among others. As you may know, the State of Michigan, USA,
