Map Collection

WebOffice 10.9 R4 introduces a map collection concept, e.g. it is possible to

1.define a set of maps as default map collection (administrator) to make those maps available for the user

2.dynamically add a map (e.g., of type OGC WMS or ArcGIS Server Internet Service, ArcGIS Online and more) (user)

The map collection concept provides a lot of advantages

•blending maps

•displaying one map on top of the other

•quickly and easily switching between different maps within the WebOffice 10.9 R4 clients

•displaying maps only in certain scales (minimal and maximal scales)

The properties of each of these maps can be changed by the administrator (defining the default properties) and by the user:

•Maps can be set to visible or invisible,

•The map transparency level can be changed. This is especially useful for blending multiple maps,

•For services added dynamically by the user, the maximum wait time can be set by the user,

•For services added dynamically by the user, the position of the map within the map collection can be changed.

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 10.9 R4 clients (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 pre-rendered cache are displayed.

These two map images get displayed one on top of the other in the WebOffice 10.9 R4 clients. This makes map display still very fast although a dynamic map service is involved.

This scenario is recommended if you need to display static base data as well as dynamic data. See also chapter Combine Dynamic and Static Geodata Properly.

Dynamic

At one point of time only one dynamic map service is displayed in the WebOffice 10.9 R4 clients.

This scenario is recommended if you do not have static base data that could be cached at all.

Combined ArcGIS Online/WMS/OSM 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 service (like ArcGIS Online, WMS or OSM).

This scenario is recommended if you do not have static base data in house but there are external sources available.

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.

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

•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

•It is recommended to configure WebOffice 10.9 R4 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!

•Map visibility and transparency level get configured in the Table of Content (TOC) respectively in the Map Views configuration.

•See chapter Map Collection for configuration details in WebOffice author standalone.
