[Community] ArcView Question

Hi Michael,

The formats you are referring to are graphics formats that are useless for GIS or web mapping.  The final rendered product for a WMS is such a graphics format but the data that needs to be used to generate that final rendered image has to be stored in some database format (dbf for shapefiles, postGIS ...).  Or maybe I don't understand what you are referring to ?  You don't need to export your maps before using them in PrimaGIS : just use the data.

As to the PrimaGIS demo site, Kai will need to chime in on this but my understanding is that the aim was not to show off how increasing amounts of geographic features are shown as one zooms in but rather to show how *content* (in the sense of Plone-managed content objects) can be tied to geographic locations.  Kai could have tied Plone news items to points on a map.  

It is crucial to understand that *any* Plone content object can be tied to a geographic feature with PrimaGIS, which makes it quite a bit different from a "simple" web mapping application IMO.  You could choose to tie your project descriptions (if you had them stored as Plone content) to points on a map so people could have a spatial query into your project description objects or reports or what not.  More so, a PrimaGIS object is itself a Plone content type so it can use all the CMS machinery (workflows, access permissions and eventually maybe versioning).  For example, you can hide layers to certain users by virtue of their workflow state (a "public" layer will be visible only to site members).  Go to the site as anonymous and see N layers.  Log in as a regular member and see N+x layers.  Log in as some special member type (reviewer, admin ...) and see n+x+y layers.  There is a lot more that can be done using a CMS like Plone e.g. create groups of users and let them share layout preferences, layer selections, predefined views which I'm hoping to help build over the coming months.

HTH,

Yves

Hi Moisan

Basically, the default files that ArcView produces.

I've had a look at the export options and these are as follows:

   * Placeable WMF
   * Windows metafile
   * Windows bitmap
   * Postscript (EPS) 
   * Adobe illustrator
   * JPEG
   * CGM Binary
   * CGM character
   * CGM cleartext

Yes, I was referring to the PrimaGIS demo site and wondered if you could zoom in to city level and see streets etc. 

Thanks for your help

Michael

Hi Michael,

If "files created in ArcView" means shapefiles, then you'll find examples in the ZCO and PrimaGIS project docs.  As to a more detailed zoom, what demo site are you referring to ?  The PrimaGIS demo site ?  Does "more detailed city information" mean geographic objects ( e.g. roads showing up) or just more text as one zooms in ?

Cheers,

Yves Moisan

Hi

Is it possible to publish files created in ArcView on to Plone/PrimaGIS at all?

Also is it possible on the demo to zoom in to more detailed city information? 

Thanks

Michael
