how to make a map project in envi
i have there data( latitude,lontitude,and land surface temperature )
how to make it into a envi file(*.img) with map project(albers)

Well, I think the easiest thing to do would be to make a
GeoTIFF image that you could easily read into ENVI. You will
have to project your data to create the projected image.
If you are familiar with the MAP_PROJ_*** routines, I would
use those. Otherwise, you might get away with MAP_PATCH.
...Map Projection Conversion in ENVI
OK, I am at wit's end here.
I have opened a MISR image in ENVI. I've used blocks 10-35,
so this image is roughly over the Arctic Ocean. The
image is georeferenced to a Space Oblique Mercator
map projection. All well and good. The image runs
through (and extends outside) a rectangular grid I
am using for a study area.
I now wish to convert this image to a Lambert's Equal
Area projection, using a particular 500m grid that represents
my study area. (The original data is on a 275m grid.) I
can successfully use the Convert Map Projection selection
from under the Map menu to d...converting map projections in IDL and ENVI
Dear forum users,
I want to convert the projection of georeferenced images whereby I specify
the coordinates of the upper left pixel in the resulting image (so the
pixel exactly match other georefenced images I have). The ENVI GUI
convert map projection function allows for this. However I need to use
IDL commands. Unfortunately, the envi_convert_file_map_projection doesn't
allow me to specify the coordinates of the upper left pixel in the result
image, as far I can tell. Any suggestions for doing it anyway?
Thank you in advance,

I have a file in ENVI's memory that is in one coordinate system
(Washington State Plane North), and I would like to convert it to
another coordinate system (geographic longitude / latitude). How can
I do this in ENVI?
I tried >Map >Convert Map Projection, but I must be doing something
wrong in the 'Convert Map Projection Parameters' screen. Under
'Output Projection and Map Extent', it wants to know the coordinate of
the upper left corner (I assume this is in the *new* projection
system). I put in my best guess at what the upper left corner will be
in lat/...converting map projections using ENVI
i have a simusoidal map which i want to convert into lambert conformal
i made a customize lambert conformal conic projection. but when ever i
tried to convert it it would give the following error" array dimensions
must exceed 0"
but when i tried to convert a world demo inbuilt in ENVI and using the
customized projection it worked!!
i dont know where i am going wrong
any help would be appreciated

I've been fighting with this problem for weeks and have finally given
up on solving it myself. I hope that someone with more experience
manipulating maps in ENVI can offer me some advice and guidance.
I have an image file (actually many such files) that is written as an
hdf. The data in the file have been geo-referenced and projected.
Some of the projection parameters (Mercator, limit, central azimuth)
are included in the file as attributes of the scientific data set, but
there are no explicit latitude and longitude values corresponding to
the pixels in the image in the file. ...Project newbie asks...well what about ENVI projects?
Just got ENVI 4.5 with IDL 7.....so i'm getting used to the workbench
now (yikes! - but so far so good). I'm doing this as a complete
newbie to the concept of IDL projects. I knew pre-Workbench IDL
versions had projects, but never really had a need for them so i
ignored the whole thing.
Now, however, i find myself writing a bunch of code that i want to
distribute to several people, and the idea of setting up a project
immediately starts to seem attractive. Here's the thing though....the
code i'm writing is for ENVI. Basically i've got a bunch of .pro
files t...map projection
Does any one have good ideas about adjusting the same map projection
from C to IDL?
I have a 800*800 in Polar Stereographic in C and trying to adjust it
in to IDL, but always cannot find the perfect match. :( Thank you

Should be no problem with this if you are using
the MAP_PROJ_**** routines. We do this routinely

It is really unclear what you are trying to do. Could you
Also, this does not seem to be a question about C. If it is
really a question about an algorithm, you should consider finding
a newsgroup about that class of algorithms instead.
