GSoC 2009 gvSIG WMST-C Weekly Report 20090529

2009-06-15T18:23:41Z

Wiki-Mornsunrain:

Dear All,

I am Xi Chen working on the WMST-C support in gvSIG project. Recently I was busy on two algorithm contests, and lab paper writing. I was a little multi-task. So Dear Administrators here like Wolf and etc., please beg your excuse for my so late report.

Just on my way, here is my first week report:

==Done==
# Read the documents and papers to get familar with correlative OpenGIS Standard.
# Explored some prototype like OSM tiles and Spanish Ortophoto tiling server provided by my mentor Luis.
# I used Eclipse as the development environment and checked out the source code of gvSIG by Subversion from our SVN server.

==Plan==
# Look through gvSIG codes.
# Investigate how to intergrate WMST-C support in gvSIG.
# Continuously survey on how the WMST server runs and how the client cooperates.

==Bottleneck==
Because of the narrow bandwidth from Spain to China, partial codes of gvSIG are hard to check out. It always halts on half way of transfering. Does anyone can settle this problem? Please give me a hand.:D

Best Regards,

Xi CHEN

Dear All,

Here is my 2nd week report of GSoC 2009 project gvSIG WMST-C:

==Done==
# Read the ducuments of gvSIG desktop application and the developer guide manual.
# Succeeded in building up testing environment and checked out all the necessary source code of gvSIG by Subversion from our SVN server.
# Familiarized with the methodology of gvSIG development and implemented some simple extensions.

==Plan==
# Continue to explore the architecture of gvSIG desktop.
# Implement some complex libs, exts and plugins.
# Continuously survey on how the WMST server runs and how the client cooperates.

==Bottleneck==
The majority of the detailed API manual is written by Spanish, as well as some annotations of reference projects. The inter-language traslation is currently the biggest challange for me. Sometimes there are limited references for me to research my subject. So I think I should pay more time on communicating with my mentor in the future.

WMS Tile Caching

2009-06-02T13:37:12Z

Wiki-Mornsunrain: /* Interested Parties */

== Goal ==

The goal of a '''WMS Tile Caching''' proposal, perhaps ''WMS-C'' for short, is to find a way to optimize the delivery of map imagery across the Internet. The proposal needs to offer ideally some means by which map clients can fetch tiles from existing servers, in such a way that the images can be cached on the server, or at an intermediate location, or even be completely pre-generated, if desired. Further, the proposal needs to offer a way of advertising that a cached tile set is available for a given layer from a particular WMS or WMS proxy. The proposal should leverage the existing investment in OGC-compliant WMS servers on the 'Net.

The two main questions to be addressed are:
# How does a server advertise its cacheable image tiles?
# How does a client request possibly cached image tiles?

== Proposal ==

=== WMS-C as WMS Profile ===

One approach to take might be to define ''WMS-C'' (as in ''Web Mapping Service - Cached'') as a constrained profile of [http://www.opengeospatial.org/docs/01-068r2.pdf OGC WMS] that permits servers to optimize their image generation, and allows tiles to be cached at intermediate points. A WMS-C service would likely only deliver images for bounding boxes aligned to a given rectangular origin and grid, and only at particular scale levels.

The basic idea is that, unlike with WMS, two different requests for a given WMS-C tile should form the exact same HTTP GET request. This invites several constraints on WMS ''GetMap'' requests:

# Minimal query string arguments (i.e. no optional arguments permitted, versus §7.2)
# Fixed query string argument ordering and case (versus §6.4.1; q.v. also §7.2.2, Table 8)
# Fixed range of possible bounding boxes, computed from the WMS-C profile parameters
# Fixed precision on bounding box values (clarifying §6.5.6)
# Fixed tile size in pixels
# Fixed layer name and/or layer name ordering
# Fixed styling
# Fixed output format

Some means of identifying these constraints programmatically on a per-server basis, a la ''GetCapabilities'' might be desirable. From the table below, it appears that minimum/maximum scale (and scale quantization factor, which should probably never be other than 2) are the only suggested tiling regime parameters that would be difficult to directly express in a WMS GetCapabilities document. Is there some existing way to add custom parameters to a GetCapabilities declaration?

Note that the ''LAYERS'', ''STYLES'', ''SRS'', ''HEIGHT'', ''WIDTH'', and ''FORMAT'' arguments to a ''GetMap'' request would become fixed for a particular WMS-C tiled layer, but the WMS specification would still require the inclusion of these arguments in every WMS-C request (§ 7.2).

A WMS-C proxy or server should be free to return an exception or a redirect, if it receives a WMS request that is not WMS-C compliant, or involves a bounding box that does not correspond to a single tile in the cache.

=== Calculating Valid Tile Extents for a Given Request ===

WMS tile caching implies fixed scale or zoom levels. Typically, each valid scale level would be half that of the next larger scale. It would be worth writing reference code to help developers figure out which tiles they need to load to cover a given bounding box at a given scale.

=== Possible Tile Scheme Parameters ===

{| cellpadding="5" cellspacing="1" border="1"
| '''Parameter''' || '''Default value''' || '''Specifiable in WMS GetCapabilities?'''
|-
| "This service suppports tiling." || ''none'' || ''<KeywordList>'' contains the string 'tiled', perhaps? (§7.1.4.5.3)
|-
| Projection || EPSG:4326 || ''<SRS>''
|-
| Maximal extent || (-180,-90,180,90) || ''<BoundingBox>'' (§7.1.4.5.7)
|-
| Number of horizontal and vertical tiles at the maximal extent || ''none'' || Could be implied by ''<ScaleHint>'' (§7.1.4.5.8, but note that the format is weakly specified)... Alternately, could use ''<DataURL>'' (§7.1.4.5.14)
|-
| Tile size in pixels || some power of 2 || <Layer> attribute ''fixedWidth'', ''fixedHeight'' (§7.1.4.6)
|-
| Minimum scale || ''none'' || ''<ScaleHint>'' or ''<DataURL>'' (see note, above)
|-
| Scale quantization factor || 2 || ''<DataURL>''
|}

----

== Other Considerations ==

* Would non-rectangular tessellations yield more efficient results? If so, which tessellations to consider? Also, are the processing and bandwidth advantages of a non-rectangular tessellation outweighed by the potential implementation complexity?
* Norm Vine rightly points out that a tile request basically boils (or should boil down to) Layer + Zoom Level + Row + Column. Can we define an even simpler method for requesting tiles from servers in the know? How are those capabilities advertised, if not shoehorned into WMS? Note that WorldWind basically already has a mechanism for this. Their tiling requests basically look like:

http://domain.tld/service?L=0&X=1&Y=2
* Like all caching schemes, WMS-C caches would need to be cognizant of expiration. Easy with using the proper HTTP headers. There is a wide range of freshness/staleness, with OpenStreetMap being highly volatile, and Landsat being pretty stable (until the ice caps melt ;).
* Several people (particularly Paul Spencer and Chris Schmidt) have argued that a separate ''GetTile'' request should be used. This topic probably warrants discussion.

== Distributed Caching ==

* A WMS-C standard would permit tile caching through [http://www.coralcdn.org/ Coral]. However, the World Wind community's experience has been that using Coral to serve tiles results in frustratingly high latency.
* Alternately, one could do (distributed) [[Distributed Tile Caching|peer-to-peer tile caching]] optimized specifically for geographic space, which might still suffer the latency issues associated with P2P networks.

Note: WW and OnEarth's schemes are pretty much identical, the WW client just allows you to specify arbitrary tile sizes, coverages and number of levels to accomodate a given client.

==Planned Timeline==
Draft:

# First designing raster tile support in gvSIG core.
# Adding a new renderer on the same Map Control.
# It should be defined the way a tile layer is going to be integrated with the rest of layers, attending to discrete zoom levels.
# Management of multiple tile layers with possibly different zoom levels.

Dear All,

I am Xi Chen working on the WMST-C support in gvSIG project. Recently I was busy on two algorithm contests, and lab paper writing. I was a little multi-task. So Dear Administrators here like Wolf and etc., please bug your excuse for my so late report.

Just on my way, here is my first week report:

==Done==
# Read the documents and papers to get familar with correlative OpenGIS Standard.
# Explored some prototype like OSM tiles and Spanish Ortophoto tiling server provided by my mentor Luis.
# I used Eclipse as the development environment and checked out the source code of gvSIG by Subversion from our SVN server.

==Plan==
# Look through gvSIG codes.
# Investigate how to intergrate WMST-C support in gvSIG.
# Continuously survey on how the WMST server runs and how the client cooperates.

==Bottleneck==
Because of the narrow bandwidth from Spain to China, partial codes of gvSIG are hard to check out. It always halts on half way of transfering. Does anyone can settle this problem? Please give me a hand.:D

Best Regards,

Xi CHEN

=About me=
My name is '''Xi Chen''', and you can call me '''Chauncey''' for short. I come from Beijing, China. I am a second year graduate student at [http://www.iscas.ac.cn ISCAS] (Institute of Software Chinese Academy of Sciences).

I am a GSoC 2009 student joining in gvSIG project of OSGeo Organization. My GSoC 2009 project is to implement '''WMS Tiling Cache support in gvSIG'''.

=WMS Tiling Cache support in gvSIG=

[[WMS_Tile_Caching]] has been defined within OSGeo, with a [[WMS_Tiling_Client_Recommendation]]. The aim of the proposal is to add WMS Tiling Cache support to gvSIG, in order to allow the loading of this kind of layers (WMS-Cache).

The work may be achieved by:

# First designing raster tile support in gvSIG core.
# Adding a new renderer on the same Map Control.
# It should be defined the way a tile layer is going to be integrated with the rest of layers, attending to discrete zoom levels.
# Management of multiple tile layers with possibly different zoom levels.
