In a separate post, it was suggested that a poll ought to be taken to see if there was sufficient interest in bringing the GIS module to Canvas draw so I thought I would start a new thread with that in mind.
As a geologist, I've used Canvas for 30 years and, even though a Mac user, I still use the windows version with GIS to make maps of geospatial information (an essential activity for any geologist). I've even written software for formatting tables of strike and dip symbols to plot on maps. The work flow with dedicated GIS systems is make the map in ArcGIS or what ever and then port the result to a vector drawing program to "pretty it up" for publication. With Canvas GIS, I can do all of that in one program. Especially useful is Canvas' seamless combination of vector and raster capabilities. I can warp a raster (e.g., satellite image, hill shade topo) and plot my vector data right on top. In my most recent project, using the Windows version of Canvas GIS I imported a Chilean geological map of a mine which used the PSAD56 datum and warped it to UTM/WGS84 coordinates.
Although I could continue to use the Windows version in VMWare Fusion as I do now, I would absolutely love, and pay extra for, the GIS module in Canvas Draw on the Mac.
Richard A, thanks for the link to ImageJ. Surely the best solution for ratioing.
Out of curiosity, I just tried using Transfer->Difference in Canvas Draw for overlaid Landsat imagery which had little topography (therefore without the illumination problems that ratioing is supposed to eliminate). Definitely highlighted the differences between bands and between various band combinations. Interpretable? Well, that's another question!
CanVas X Has the abi;its to perform arithmetic functions in the Scientific imaging module including division. So the question becomes a matter of finding the legacy scientific image module as well as seeing if it is present in the newer versions of Canvas. is it possible to get a legacy version scientific image module for Mac Canvas X to use until it upgrades for the Mac?
I'm also investigating ImageJ. Looks promising after a dry spell on Social Security...
My most powerful machine currently is a MacBook Pro (15-inch, 2.53GHz, Mid 2009), 2.53 GHz Intel Core 2 Duo, 8 GB 1333 MHz DDR3. running OS 10,11.8, which will be upgraded ti Sierra or High Sierra. I don't know if it will take more RAM. Considering I've been using a PowerBook G4 with OS X 10.5.6 it's been quite a jump. I'm also using a iBook G6 with 10.4.11 and an upgraded PowerMac 7300 with a G3 card, USB & Firewire & 1gb ram with OS 9.1. It's mainly used for my geologic data spreadsheets for subsurface well tops thicknesses etc.
I remember the old NIH Image, I've downloaded ImageJ and will see how well it will work. My canvas image & geology files are also typically 200-400 mb. I would really like to see if the scientific imaging module for my mac version of Canvas would work. according to the manual it should be able to. At the time I bought Canvas with GIS, I was also interested in the scientific image module but was thought it was an either/or situation . Too bad CanvasGFX won't offer some legacy support for Canvas X since they don't offer the full version of Canvas for the Mac.
I used the GIS and Scientific Analysis modules in the old Mac Canvas and
would be happy to pay for (more than) one copy of them now if they were
available. I keep a legacy Mac OS X 6.8 running for occasional access to my old Canvas X projects. I currently use three copies (legal), two in different offices, one at home. I use Arc GiS and export files to Canvas Draw, but we would save a lot of time if we could just use Canvas on a Mac.
No, we won't buy the Windows version of Canvas.
I'm another geologist chiming in again with continued push for GIS capabilities in Draw. Also wanted to mention a work-around for the MrSid files you run across. Thorsten Lemke's Graphic Converter app https://www.lemkesoft.de/en/products/graphicconverter/ can open them and convert to more usable images.
Looks like this is the geologist thread! I'm a hydrogeologist and a long-time user of Canvas, having started using Canvas when it was a "desk accessory" on a Mac Plus back somewhere around 1985 or so. I suffered through the PC-only period, so was really happy to see Canvas come back to the Mac. I do have a PC with Canvas X 2019 GIS that I use for that purpose, but much prefer my Mac, of course, so count me in as someone who would like to see GIS capabilities in the Mac version. Someone mentioned import/export of Google Earth KMZ files and I do like that. I'd also like to see the ability to import QGIS files, other than just the SHP files. Since QGIS is open source software, I would think that might be possible, but am not sure.
I even run OsX leopard on three machines just so I can still run the GIS version of Canvas for Macs - though it is getting long in the tooth. We used to purchase 20 lab copies and 5 faculty copies of the GIS version for Macs. If this was available again I know we would at least purchase 3 faculty copies and 10 to 15 lab copies.
I have also written many an email asking for Mac GIS support over the years with either no response or cloudy response. There is nothing quite like Canvas on GIS steroids and we would love to be able to use it again on modern hardware.
Anyone who wants to do some sophisticated multi band image processing should get the free MultiSpec from Purdue. Free and incredible software that even has some pretty neat experimental classification and analytical techniques. It can handle hyper spectral data and work with very large data sets.
We also have an old Mac running OS 6.8 just for Canvas X with GIS, but it's awfully slow. We would also buy multiple copies if Canvas Draw with GIS (or Mac Canvas with GIS) was available.
Adding another vote for GIS in Canvas Draw (or Mac Canvas). I use last Canvas X for Mac with GIS in Parallels running 10.6 (made sets of maps for a book I wrote and continue to reproject maps for Maplets). A little sketchy at times but works pretty well and not too bad on speed. Wrinkle on then going to Canvas Draw with these .cvx files is that symbols get munched into little squares (so, for instance, I have maps where I placed little crossed pick and shovels that were a symbol in Canvas X, but they become squares on import into Canvas Draw). GIS capability was very useful and infinitely more intuitive than ESRI's notion of ease-of-use.
I'm sure Canvas GFX will eventually bring in GIS, judging by the included Symbols Libraries, so many seem to be GIS symbols.
