Map Collection |
|
The Map collection specifies the list of map services available in the WebOffice 10 R3 client by default.
It is possible to combine map services from various sources:
•ArcGIS Local Services: The basis for such a service can be a single- or multi-data frame ArcGIS map document (MXD)
•ArcGIS Server Internet Services (SOAP): E.g. many services from Esri ArcGIS Online Services are ArcGIS Server Internet Services. Some of those services are available for free use others are for commercial use only (you need to pay for them). See http://www.esri.com/software/arcgis/arcgisonline/index.html for details.
•Microsoft Bing map service
•Open Street Map (OSM) Tile Server
•OGC WMS/WMTS Services: Many public authorities on national or EC level offer public WMS/WMTS services
•ArcGIS Online Services (REST)
These map services can be blended (combined) by the administrator or on the fly by the user.
Below you find a list of supported Map collection scenarios. Concerning Map Caches you may use pre-rendered caches as well as caches of type Cache on demand:
Scenario |
Description |
Single cached service |
At one point of time only one pre-rendered map cache (=one single cached map service) is displayed in the WebOffice client (although the Map collection may of course contain multiple services). If the Map collection contains multiple map services, then at one point of time only one map service is visible. This can be easily assured by using Table of content and Map views configuration. This is the fastest way to provide map images. |
Combined |
At one point of time exactly one dynamic map service as well as one prerendered cache are displayed. These two map images get displayed one on top of the other in the WebOffice client. This makes map display still very fast although a dynamic map service is involved. Note: This scenario is recommended if you need to display static base data as well as dynamic data. See chapter How to deal with combination of dynamic and static base Geodata? as well. |
Dynamic |
At one point of time only one dynamic map service is displayed in the WebOffice client. Note: This scenario is recommended if you do not have static base data that could be cached at all. |
Combined Internet Service |
At one point of time exactly one dynamic map service as well as one pre-rendered cache are displayed. The pre-rendered cache is provided by an external ArcGIS Server Internet Service. (You can get here free Esri ArcGIS Server Internet Services you may use :http://www.esri.com/software/arcgis/arcgis-online-map-and-geoservices/map-services.) |
Generic |
Any combination of maps contained in the Map collection is possible. Each of the maps has its related transparency level and its transparent background color. Note: Blending of map images needs a lot of processing on the server, so this generic scenario is very flexible but anyway is the slowest of all listed scenarios. |
Rules for generic map collections |
It is possible to display: - multiple dynamic map services - multiple caches - multiple dynamic map services on top of multiple caches
Note: - If combining caches and dynamic services the dynamic services always have to be on top so the client can request the cache tiles. - If using caches of type cache on demand the services will be used as cached map services although the first map request per area will be returned by a dynamically generated image. |
Map collection scenarios
Note 1: It is recommended to configure WebOffice 10 R3 projects which make use of ‘Single cached service’ or ‘Combined’ scenario only. Only these two scenarios provide the performance advantages of a state of-the-art web mapping application!
Note 2: Map visibility and transparency level get configured in the Table of content respectively in the Map views configuration.
The Map collection provides some properties to better control handling of the map services:
Map collection - WebOffice category
Property |
Description |
Main map |
Specifies the default map service of the map collection. The default map service is characterized by: •It provides the main content to the map collection, •It must be available. If not then WebOffice client displays an error page and ends the user session, •Must be a service of type ArcGIS Server Map Service (local service) |
Provide discrete scale levels |
Specifies if only discrete, fixed map scales are available for dynamic map services (Yes). Note: Explicitly provided discrete scale levels will be displayed in any case. In combination with cached map services there can arise the following cases: - a) A discrete scale level is defined that is not supported by the cached map service and lies beyond available LOD (Level Of Detail) levels of this cached map service (e.g. very large scales). When selecting this scale, the concerned cached map service will not be displayed. - b) A discrete scale level is defined that is not supported by the cached map service and lies within the available LOD levels of the cached map service . When selecting this scale, the concerned map service will be integrated dynamically. - c) The cached map service is displayed dynamically in all LOD levels due to a different projection, then the service will be displayed in all provided discrete scale levels.
Note: For a detailed scenario of combining a cached map service with a dynamic map service of different scale, please, see chapter Extend discrete Scales of an external Service.
Note: In WebOffice flex client the configured discrete scale levels will be ignored if they are contrary to existing scale levels of cached map services. |
Discrete scale levels |
List of discrete scale levels. Is only used if 'Provide discrete scale levels is' set to Yes If e.g. scale levels 1000, 2500, 5000, 10000 should be available in the WebOffice client then specify 1000|2500|5000|10000 as configuration value. Note: Bing maps and OSM use the following LOD levels: 9244648.868621042|4622324.434310521|2311162.2171552605|1155581.1085776302|577790.5542888151|288895.27714440756|144447.63857220378|72223.81928610189|36111.909643050945|18055.954821525473|9027.977410762736|4513.988705381368|2256.994352690684|1128.497176|564.248588172671|282.1242940863355|141.06214704316776|70.53107355442746
Note: In WebOffice flex client the configured discrete scale levels will be ignored if they are contrary to existing scale levels of cached map services. |
