I got a question. Does the polyline draw should have a “buffer zone”. I ask this because, i don’t get one.
I need to do a buffer around a polygon. Do you have any idea ? I should maybe think about getting the center of my polygon and calculate a circle like you did…

Thanks in advance for any answer.
Great job again.

I’m super close getting this proxy to work … I seems to be exactly what I need, but am getting a 401.3 (Access Denied) error.

I’ve given ASPNET and NETWORK service full control on the directory (all files/subs), and IUSR_ read, write, execute, restarted the app pool (and IIS) …

Have you come across this issue or got any other directions? Please Am in IIS 6 on 32 bit Win Server 2003.

It would be really good if you could provide any pointers as to what is missing which causes this issue. Thanks in advance.

The use case I needed the above code for was for a simple mapping page that needed to add in WMS layers from any remote server.

It was to install on IIS / Windows, so setting up a Python CGI proxy seemed overkill, and also I’d have to whitelist all sites.

Its not going to replace all the features of a proxy (though it would be nice to have a plugin that used YQL through Openlayer.Proxyhost), but simplifies some setups.

Although I am not a MS software user – and happy with PostGIS -, I wonder if it will also work with SQL Server?

Could you Help me, plese?

I have a dude about off a missing Library from MSSQLSpatial Data, I’m searshing for the complementoff the sql server data Spacial (geography and geometry) for the command OGR for console, cold you sendme the step or links, about this?

a lot to thanks!

I am using VS2010 and i checked if python27.lib is accessible and everything seems fine. Can you please help me

I made a compile with all components including zlib and libssh2. Now everything works fine! Your tutorial helped to get the compile running!

Greetings!

at haxx there are only binary files for windows x64 (curl.exe) but I need a dll for my app. I can complile a x64 lib to include in my project and to satisfy the compiler but the dll compiled with this lib has no sll and no zlib. So when accessing SSL or compressed pages, I only get encypred data. For the 32bit version I only have to replace the libcurl.dll and so I intend to do with the 64bit version, too.

Thanks

It appears there is now a compiled version of cURL with (and without) SSL available on the download page at http://curl.haxx.se/download.html

Maybe give this a try to see if it includes zlib. Let us know the outcome!

Thanks

var wms = new OpenLayers.Layer.WMS(“My Layer Name”,”http://myserver.org/tiles/tilecache.py”, {layers: “mylayer”});

2. Thanks for the info – not really needed to seed a cache as yet. You could always pass in a workingdir parameter, or hardcode it if you only have one cache.

BTW, as a sense check, downloaded your x64 bit version and the 2.5.4 amd build you linked – this “works”, although complains about a ctypes module not being present in python. I checked and it seems to be there in 2.7 builds but not the 2.5.4 for some reason?

have joined the pyisapie email list now so will try and stop bugging you now!

What I have found useful when getting errors is to use Process Monitor to see what DLLs Windows is looking for, and any errors if it can’t find them or if it does not have the correct security settings.

Take a look at http://geographika.co.uk/setting-up-python-on-iis7 which goes through the set up steps in IIS7. Previous versions should be similar.
If you just installed Python on the server then try a reboot to make sure the Python environment variables have been set.

I’ve successfully compiled this project to 64bit against Python 2.7. However, when I set up the ISAPI filter in IIS I keep getting a

The specified module could not be found. (0x8007007e)

error. As far as I can tell, IIS has full access to that file (I’ve gone as far as giving the Users group and IUSR and Network Service full read/write access). Is there anything else likely to be going on here? Not sure if there might be issues loading the python bindings or something? Any ideas would be much appreciated!

In my case I need to pass data from local server to the linked one. If I use OpenQuery I need to convert every field to a string and concatenate them an execute de INSERT statement for each row.

Any other idea? Thanks.

Thanks for this post – just what I needed this morning!

Let me know how you get on. I’ll try and turn my notes into a post at some point. I think there were a couple of changes I have to make in the TileCache scripts themselves due to Python errors.

you said, that you were able to get TileCache running on IIS7 with PyISAPIe. Could you give me a hint, how the original tilecache.py has to be changed?

——————————
from TileCache import Service, cgiHandler, cfgfiles

if __name__ == ‘__main__’:
svc = Service.load(*cfgfiles)
cgiHandler(svc)
——————————

I guess, since it isn’t a CGI script, that has to be adopted… currently I get:

Request handler failed

Traceback (most recent call last):
File “C:\Python25\PyISAPIe\Http\Isapi.py”, line 49, in Request
raise ImportError, “[Loading '%s'] %s” % (Env.SCRIPT_TRANSLATED, str(Val))
ImportError: [Loading '\\?\C:\inetpub\wwwroot\tilecache\tilecache.py'] ‘module’ object has no attribute ‘argv’

I found your entry interesting thus I’ve added a Trackback to it on my weblog …

A new Gephi plugin has just been released: GeoLayout. It allows to use latitude/longitude coordinates to set nodes’ position.

You can download it from this page (http://gephi.org/plugins/geolayout/) or install directly from Gephi (Go To Tools > Plugins).

The author is looking for feedbacks, don’t hesitate to come to the forum!

It works great IMO

You don’t happen to have a copy of the dll do you,

Cheers Jonathan

from PyISAPIe import Env
from hashlib import md5
import imp
from os import stat

Handlers = {}
TimeMap = {}

def Request():
Script = Env.SCRIPT_NAME
Key = Name = ‘__’+md5(Script).hexdigest().upper()
Handler = Handlers.get(Key, None)
mtime = stat(Env.SCRIPT_TRANSLATED[4:])[8]
if not Handler or TimeMap[Key] < mtime:
Handlers[Key] = imp.load_source(Key, Env.SCRIPT_TRANSLATED).Request
TimeMap[Key] = mtime
return Handlers[Key]()

While I’ll be posting some details on the PyISAPIe list later regarding changes in the new version to make this process easier, I just thought I’d mention a few things that could help you in the future-

- PYI_PY_VERSION can be defined in the project settings, under C++/Preprocessor. This is the easiest way to compile for different versions because no source changes are required.

- You can add additional include and library directories at the project settings level rather than the Visual Studio settings level, which can help in some cases.

- If SubWCRev wasn’t working from Visual Studio but was from the command line, all I can suggest is to log out and back into your Windows account to be sure that your PATH has been updated everywhere (it works in Windows 7 right after installing TortoiseSVN).

Thank you for this guide, I’m positive that it will be a great help to those compiling the project themselves.

It is nice to see how “nice” online applications can help us documenting

With regards to where cloud computing could be useful, hosting the mapping engine and database in Azure could provide a powerful, scalable back-end for many different client map viewing applications.

I guess the sub-regions also help government departments from keeping within data legislation rules.

1. SQL Azure is a multi-tenant, scale-out relational database service. It’s not “hosted SQL Server” a-la-SaaS style. The implementation today, in a nutshell, allows you to interact with the SQL Azure application, but each logical database is actually managed as 3 separate replicas underneath the SQL Azure application, which then use SQL Server as the relational database engine. The SQL Azure application then load-balances and synchronizes the incremental changes across those 3 replicas. To you it’s looks like one SQL Server database over the Internet but SQL Azure uses this strategy to ensure resiliency and scalability. It’s not the same as any hosting solution anywhere else.

2. The “Currently you can’t bring your existing on-premises Windows Server, SQL Server to Windows Azure, SQL Azure” comment was intended to point out that developers cannot bring server software to deploy into Windows Azure and SQL Azure; as you can tell from the first point above – Windows Azure and SQL Azure aren’t hosted servers. Thus, from a development model perspective, Windows Azure and SQL Azure actually do support current applications and databases created locally and then uploaded into Azure. In fact, for SQL Server, all your views, stored procs, functions, and data, can all go directly into SQL Azure. There are some differences but today we’re at about 98% feature parity and are working towards 100%.

3. Similar to your observations, and as Ed Katibah pointed out, SQL Azure isn’t ideally suited as a replacement for a local SQL Server database. This also goes back to what does cloud computing represent? Many people think cloud is simply someone else’s data center that runs the same things for rent. In our case, Windows Azure and SQL Azure, as they are implemented as a different type of technology, they’re not simply hosted versions of software that you have locally. And thus, they’re ideally suited for different types of workloads and application scenarios. However, some laws of physics still apply, as an application that uses a relational database as a back-end will continue to operate better having the database local as opposed to over the Internet. And that means many applications that use SQL Azure will also be more ideally suited to be hosted in Windows Azure as well. Other scenarios also evolve around data sharing leveraging data integration techniques.

Just my thoughts. Best! -David (blogs.msdn.com/dachou)

Here is information from our web site: Data Transfer Details: “Our data transfer rates are determined by the region in which your solution is deployed. Data transfers between Azure Services located within the same sub region are not subject to charge. Data transfers between sub regions are charged at normal rates on both sides of the transfer. A sub region is the lowest level geo-location that you may select to deploy your applications and associated data.

Glad that you were able to get the fixes for the issues encountered. One quick comment about the error and it fixe in MI Pro 10.0.1 maintenance release. In the release notes, while one can argue that the description might not be very explicit on the error and its message, here is the reference to the issue (in the release notes):

”
C15797 When ArcGIS® 9.2 or 9.3 is installed on the machine MapInfo Professional closes unexpectedly when
opening a Universal Data File.
Resolution: Issue is resolved.
“

All the best,

Jonathan
