I would like to upgrade my 8.0.28.0 to the current version of Manifold 8. I'm running Windows 7 Pro and have no plans on upgrading that, at least with this computer. I've run into a projection not listed and see a newer version of 8 has it. I've used the program sporadically over the yearsas a volunteer to bill maps and analyze data. After reading the process to upgrade the program I'm a little confused andconcerned about pushing any buttons. I have a good serial number. I need some help, thoughts. Thanks Scott

Seems like you could use the custom "Edit - Assign Projection" process for a one off job like this without going through all the upgrade travails.

Cut and paste in the parameters from the newest V8, give it a memorable name, and verify your results.

What is the projection?

It sounds very unlikely.

More probably, you are doing something wrong.

After reading the process to upgrade the program I'm a little confused

No worries, it's easy to upgrade:

1. Uninstall your current 8 installation.

2. Download the latest 8 Base build from the 8 Downloads page and install it. Done!

If your Windows system is 32-bit, download and install the 32 -bit Base build. If your Windows system is 64-bit, download and install the 64-bit Base build.

Once you get more confident about how to use installations you can also download and use the latest Portable build. You don't have to uninstall the Base build if you also want to use a Portable build. You can have both installed and in use at the same time on the same system, if you want.

I believe it is wkid 3857 or something like that and after spending a couple hours trying to figure it out I gave up and had a friend convert it to lat lon for me and it worked just fine. I will try the upgrade, it sounds fairly easy. Thanks

The upgrade was quite simple but that didn't help with the project issue. My friend used Manifold 9 to convert the file for me. Do I need Manifold 9 to convert from this projection? or is there a simple way to add this projection to Manifold 8."WGS_1984_Web_Mercator_Auxiliary_Sphere",

Thanks Scott

No. In Manifold 8 that projection (or pseudo-projection, depending on who you ask) has a strange name.

It’s called “World Geodetic System 1984 (WGS84) Auto”.

(That is from memory—it may begin with “WGS84” instead.)

Google maps linked in v8, currently comes in with the "Mercator" projection and "World Geodetic 1984 (WGS84) Auto" datum.

I seem to remember that there used to be a "Web Mercator" projection but my memory is crumbling weekly. I remember that as I chose for a generic Mercator, the non-"Auto" version for static files, and the "Auto" version of WGS84 any time I would play with online pseudo-Mercator services.

It appears that the latest version of manifold 8 does not list the projection WGS 84 / Pseudo-Mercator (EPSG:3857) and Manifold 9 does. Looks like I need to purchase 9.

Perhaps you missed my post above.

In any case, I wasn't very clear. Sorry about that.

To get EPSG:3857 in Manifold 8, select "Latitude / Longitude" as the projection, and "World Geodetic 1984 (WGS84) Auto" as the datum (in the next box below).

That did not work, perhaps the projection is not WGS 84 / Pseudo-Mercator (EPSG:3857) here is the projection file. Thanks for the help

I've put you wrong a second time. A real brain-fade, sorry.

What I should have said (though at this stage you may not believe me) is:

To get EPSG:3857 in Manifold 8, select "Mercator" as the projection (found under Standard > Cylindrical), and "World Geodetic 1984 (WGS84) Auto" as the datum (in the next box below).

That worked. Thanks Scott
