I'm trying to display on the web (read as create a GIS Web app) topo data layers stored in a POSTGIS/POSTGRES spatial database using mapserver. My problem is, although i happened to come across different gis frameworks that I could use, my lack of experience on using mapserver in the first place makes me indecisive of which framework to use. So what is the easiest framework out there to use? I'm using a MS4W pre-packaged mapserver binaries, and i've installed almost all of the additional packages (frameworks) from their site.
Thanks for the help!:) I
Mapfish (I think python and C based and ideal with mapserver)
GeoServer (java based)
Featureserver (RESTful, light and effective)
Other interesting links:
GEOEXT provides an excellent extension for openlayers
Boston GIS provides excellent tutorials so does Paul Ramsey and Chris Schmidt
The mother GIS - Free Open Source Software OSGEO
FreeGIS - Continually updated list of free and related GIS software
I've used Geoserver and Feature server on multiple occasions, and never got deep into mapserver. I know that Mapserver has a big community and they love helping out, check them out on IRC and their mailing list.
We have developed an interface called OWGIS for displaying GIS data.
Website: http://www.owgis.org
Description:
The OWGIS (Open WebGIS) is an OpenSource Java Servlets web application that creates WebGIS sites by automatically writing HTML and JavaScript code. The WebGIS sites are configured by XML files that define which layers will be displayed on the maps as well as the texts to be used on the interface. OWGIS's most notable features include animations, veritcal profiles and vertical transects, various color palettes, dynamic maps, downloadable data, and multilingual interfaces. All these features are created automatically without any additional web programming.
Since you already got MS4W installed. The easiest way to publish a map service from Postgres is from MapServer which is component of the ms4w.
To start publish wms from MapServer,
1) Read thru the documentation of Mapfile which is the service definition file of how the WMS configured.
2) Read the ogr postgis connection documentation. You would be able to write the database connection follow the instruction pretty easily.
3) Once you got the valid Mapfile with correct postgis connection string info, you are able to publish the WMS for your topos.
MapServer is very powerful and easy to use. The file based service provide a lot of flexibility which is critical when you need publish something dynamically.
GeoServer is very popular too and has a gui which is extremely easy to use, by several click and your services are ready to go.
Other solutions are also available as well. But consider the community user base and tech support. I would recommend using MapServer or Geoserver for your case. We had our Mapserver holding USGS topo services as well, which is very stable,flexible and salable so just some FYI.
Hope it is helpful.

I am trying to find a good place to start for a potentially SAP related project.
Suppose I wanted to develop stand-alone software that could connect with an SAP ERP (S4/HANA) system and analyze material management and accounting data. What resources would I need to accomplish that? Where could I get an SDK/the proper training for this? How would I get a system to experiment on? I've tried Googling this question but there doesn't seem to be clear authoritative information on this and what I find also seems to be mostly about SAP Business One, which is a different product.
Insights would be much appreciated!
Thank you in advance,
Joshua
You must use REST/OData to connect to ECC and Hana S/4.
Currently, SAP has around 800+ REST APIs for SD/MM/PP/FICO, and almost every quarter, new APIs are added to Hana S/4.
You can check all the available APIs # https://api.sap.com/package/SAPS4HANACloud/all
You can check out the demo below if you want to view an application that provides similar functionalities.
https://demo.inoerp.com:8090
Select Hana SandBox. This is a single app that provides similar functionalities for Oracle, SAP, Dynamics etc.
If you need an API that is not yet published. You can also create your own APIs using ABAP
Regarding technology - You can use anything Java(Springboot/ADF), C# .net, node.js. You will be fine as long as you stay away from the SAP technology stack (i.e., ABAP and UI5 :-))
Need help on the following question:
We have a set of DWG files which we want to manipulate (in a program), put some layers and put some polylines on the original DWG and save the DWG (preferably using Python or C++). This has to be done on a virtual machine.
Please let me know
If this can be done on Linux machine and also what license shall be required.
If not then for windows what license shall be required.
Can this be done without installing Autodesk on the VM (utilizing only the runtime). If so how.
Thanks so much.
You have tagged autodesk-designautomation, so using Forge Design Automation this can done, it doesn't require any license or hardware, it is a cloud service.

Anybody recommend any backends or frameworks for Forge?
I'm seeing resources for Nodejs, PHP, .Net Core and others which are for the backend.
Are any of these any more convenient or dependable with Forge than the others?
I also know Python and thought Django would be another option but I don't see too many resources on the Python side of things.
Any perspectives on the tools (pro or con) would be great.
The more I understand the kinds of tech stacks, user projects and ways people use Forge to expand on BIM 360 and other APIs the more it can help me and the community get familiar with the service.
This relies completely on the excisting stack used by your company. Forge is a collection of API's accessible via endpoints.
Any library just abstracts the calls away in a accesible way. I've had moderate succes with the dotnet core Forge package, it works very well but you are giving away some strict typing.
If you dont wanna be bound by abstractions made by other people, create your own ! This will ultimately lead to the most lightweight solution since you are only creating what you need.

GIS is not really my expertise and need advice from experts here. Pardon me for my incorrect terms. I have a client asking to develop a system which provides API to consume data from their POI, PA and MPA datasets (in shapefile). Question is, what are my options to do this? Should I develop the system from scratch by maybe converting the shapefile to GeoJSON, or us there any opensource/paid solution already made for this use case? Any help/tip/advice would be much appreciated! Thank you!
You can try Geoserver. I know people without GIS or technical knowledge who managed to publish geodata with it on the web. The vector data / JSON API is an implementation of the OGC WFS standard - which might come handy if later your client decides to plug the data in something like Leaflet or OpenLayers (or most other GIS frameworks for that matter).
Note that GeoServer is a great standalone solution. But I'm not so sure it is your best option if what you are describing is just one part of a more complex system.
(I hope this is a valid question)
As I stated in my title, I'm looking for a fairly easy to moderately easy idea for some sort of online raster analysis map. I'm familiar with ESRI and their really awesome API, as I'm hoping to tackle something on that front. I'm also open to using the mapstraction lib.
Does anyone have any ideas for me?
Thanks!!
I'm not sure you mean image rasters or data rasters. This uses open source packages: MapServer and an AJAX client MsCross. It generates data rasters on the server and displays them in the browser. The rasters are contour plots for a plume of contamination in groundwater.
If you are already familiar with ESRI, then you should look at the ESRI Flex API ESRI Javascript API. You can use both of them to fire up Server side Geoprocessing services.
There are so many ways to skin the cat...
You may want to check the Publishing a GeoProcessing Service section of ESRI help
The basic idea is this... you use ArcMap/ArcCatalog to author a Geoprocessing Model (I am assuming you are familiar with this), which you later expose in an ArcGIS Server as a Geoprocessing Service. Publishing a model as a service is pretty easy provided you already have an ArcGIS Server configured - see the links I provided you above.
Then you can either use the free ArcGIS Explorer application to consume that GeoProcessing Service or write a webapp using Flex, or Javascript or DotNet or even python to consume that webservice.
And yeah, don't consume the webservice synchronously - stick with async.
You do unfortunately not write, what exactly you need. Do you want to display maps on a web page or in a application?
In the latter case i would recommend using http://www.openstreetmap.org/ it seems to be a little tricky in the beginning, buts data base gets better and better. A number of renderes exist, which you can integrate into your application.
