zigGIS Usage Experiences

Rate this Message:
Sorry for the cross post, but the zigGIS list only has 9 subscribers
with a ton more downloads than that. I'm curious about any experiences people are having using or even *trying* to use zigGIS. Is it working? Anyone need any help? Any constructive criticism? ... I haven't heard a peep yet. Thanks. -Abe _______________________________________________ postgis-users mailing list postgis-users@... http://postgis.refractions.net/mailman/listinfo/postgis-users |

Hello Abe
you made a great job with your ZigGis! The ArcObjects code is amazing! maybe you can give me a help I compiled your code for using it with ArcGis 9 (i made some little modifications at the code to get this) and .NET 2.0 It compiled fine, but when I start ArcMap and I add a PostGIS layer, it adds the layer on the TOC but nothing is showed/drawed on the map. Looks like geometries are not read from the shape column. I am wondering if you are still on this project, and maybe you could give me some help, or if I am on my own and must deeply investigate/debug myself the code in order to find what is not going properly best regards Paolo Corti GIS Developer http://www.paolocorti.net

I'm not sure if there was a breaking change since I last worked on it,
but there was actually a lot of functionality already working; Features rendering, Identify, and Table View all worked. I'm pretty sure I had asbinary() in my querying already. Maybe I'm wrong. Anyhow, this is what should occur. Do a lookup on the PostGIS registry table and find what column is the vector column for your table in question. Then, anytime a query goes to the Npgsql driver, that geometry column should first be wrapped with asbinary(). Good luck. -Abe On 11/28/06, joshua.uyehara@... <joshua.uyehara@...> wrote: > Hey Paolo, > > Abe isn't working on it anymore, but I have been occasionally plugging > away at it myself.

Hello Joshua
and thanks for the workaround, I will test it as ASAP It is very possibly that we could join to make some modification at ZigGis, as far as I would like in my spare time to write a connector for PostGis for ArcMap. First I was looking at PgArc (I also migrated that at ArcObjects 9), but I think the best approach is like ZigGis does, without a proxy shapefile, but directly reading the data. I have one more question, before going on. In this mailing list it was claimed, I think just from Abe, that ZigGis can read and also WRITE PostGis data. Is this correct? Because from what you are writing seems that ZigGis can just read and not write, and maybe I could be not interested in continuing using ZigGis. In fact I have decided to write in my spare time a full Read/Write PostGis connector for ArcMap. But before doing that I would like to deeply investigate if ZigGis already does the job. Best regards Paolo Corti http://www.paolocorti.net

Yes Abe
I have seen your 3ed at support.esri.com no one seemed to help you I am sorry Have you checked out these 3 alternatives at ArcObjects help (under extending arcobjects)? 1) Custom Layers 2) Plug in data sources 3) OGIS compliant OLE DB providers Plug in is not applicable (it is read only), but the other 2 are viable Custom Layers also from .NET I was investigating if also OGIS OLE DB could be developed in .NET (in the Help is written only VC++ realistic for implementation, but maybe this comment is obsolete now) in any case, congratulations for your great job, even if ZigGis do not write ;-) Paolo

General discussion :)
I am using pgArc for my PostGIS/ArcMap connection. It does both read/write with some bugs. I hope to post the changes to 9.x soon on the pgArc site. There is also another effort at: http://datashare.gis.unbc.ca/transhape/ that uses a different approach. I looked at zigGIS and passed only because I don't program in C#. Finally, Would there be any interest in a ArcToolbox version of PostGIS/ArcMap ?? I have done a lot of work on toolboxes and think I could get a proof of concept going pretty soon. Advantages would be Python as a scripting language, the GUI is drag and drop and the tools could be modular (One for read, one for append, one for update, etc). No compiling would be necessary and the scripts could be used in Model Builder. Comments?? Bruce Rindahl -----Original Message----- From: postgis-users-bounces@...

I agree. And I even initially went down the route of a custom layer.
I think it fell short right about when I started exploring editing capabilities ... IIRC it's not possible with a custom layer. I also explored the OLEDB data source and that had its restrictions somewhere too. -Abe On 11/28/06, joshua.uyehara@... <joshua.uyehara@...> wrote: > Of all of the approaches so far, ZigGIS is the conceptually the > 'cleanest', as it is going the route of a full feature class adapter > implementation (the custom layer approach), but it also requires the > greatest amount of work, as you have to eventually implement the > functionality exposed by about a dozen interfaces. > > pgArc is great for single users, but you run into problems when you need > concurrent access, or relationships with other tables in your database. > The same problems would plague the toolbox approach (which I assume > would basically be a front-end to shp2pgsql and pgsql2shp). > > That's not to say that the pgArc or toolbox approaches aren't worth > pursuing.
