ramp-pcar's Issues

Export Map Issue - Exporting file-based layers

When I add a file, CSV, Shapefile or GeoJSON, and then use the "Map Export" function, those added files do not show up on the image. You need to add the graphics layer on which those files are rendered to the created image.

Better description of the type of error when failing to import new layer

When importing new ESRI Feature Layer, the import would fail on heavy layer because of potential timeout. The user can hit the reload link but the layer will fail again for the same reason. It would be nice to have access to a description of the cause of the error in order to prevent user to try to add layer that will always fail.

Inaccurate GetFeatureInfo response in IE

There is a problem with IE (It's working with FireFox and Chrome) for a WMS service. The getFeatureInfo does not return the proper values in IE for the location clicked on the map. Try in the Toronto Area: http://160.106.128.113/RAMP/ramp-en.html?keys=8a6f9d25-26b5-43f9-865f-b81cc80a3900&lt=%7B%22rcs.8a6f9d25-26b5-43f9-865f-b81cc80a3900.en%22%3A1%7D&xmin=-8935316&ymin=5349860&xmax=-8707534&ymax=5459317&sr=%7B%22wkid%22%3A3857%7D

Attached image shows that the output for Toronto is coming back as Erin (to the left on the map)..

Failing to display ERSI Layers with french accented letter in their name

You can reproduce the issue by trying to add the following layer: http://geoappext.nrcan.gc.ca/arcgis/rest/services/MMS/PM_F/MapServer/1

The layer will be added in the Layer Panel but the features won't be displayed on the map and an exception is raised in the console.

Datagrids causes a continuous Loop when there are no Feature Layers

RAMP continues to loop and never completes "loading" when attempting to access the datagrids with no Feature Layers added to the interface.

Zoom Scale Dependency for WMS Layers

We have WMS layers or group layers only available at a maximum scale (e.g. http://maps.geogratis.gc.ca/wms/hydrography_en?service=wms&version=1.3.0&request=GetCapabilities&layers=hydro_features). So the user has to zoom in at a certain scale to view the data. This information is included in the getCapabilities. Is it possible in the dataset section to inform the user that he has to zoom in to view the data?

Dataset/Data Tabs

There is an issue with the Dataset/Data tabs in French. When you reduce the width of the browser, the Data tab is half gone. See image

"Disable Queries" is not documented in the Help section

Loading Animations are Inconsistent

RAMP uses several different loading animations to provide visual cues to the user. These should include text indicating "Loading" and be more consistent in the type of animation used.

French Label Problem

RAMP 5.4.0 - French label for english word "Sort" is wrong (see image). In French, we do not say "Sorte", we say "Triez".

Loading stalls on Language Change

When changing language, loading stalls.

Split the layer panel into two distinct sections (WMS vs ERSI layers)

As it is impossible to order WMS layers above ESRI layers, we would recommend splitting the current layer panel into two distinct groups. This way he will become more obvious to users that depending on the nature of a layer it may limit your ability to modify their order of appearance.

Canada View

When pressing the "Canada View" button the extent is set to the world instead of to the extent of Canada. See image

GetFeatureInfo does not work with gin WMS services

GetFeatureInfo message returned:

Aquifers - NRCan

The URL http://gin.gw-info.net/service/gin/wms/mediator/gin_en? cannot be read

Details of the operation:

The application used is: http://gcgeo.gc.ca/RAMP/ramp-en.html

The WMS services used is: http://gin.gw-info.net/service/gin/wms/mediator/gin_en?service=WMS&version=1.3.0&request=GetCapabilities&LAYERS=HydrogeologicUnit&feature_info_type=text/html&layers=HydrogeologicUnit&legend_format=image/png

Layer used is: Aquifers - NRCan

Other info

The reporter believes that RAMP does not follow the strict standard for requesting a WMS GetFeatureInfo request, and this is why the service doesn't send back the feature info.

Apparently, RAMP doesn't ask for the following parameters: STYLE and FORMAT.

Add dataset icon not showing in IE10

The add dataset icon is not showing but the link is there and working.
http://160.106.128.113/RAMP/ramp-en.html

Not able to see information in the Data section for a Feature Service

When we use the Add Dataset Function with a Feature Service, the layer is displayed but the section Data (to see attributes) is not working. The interface is running for a long time (looping) and nothing is displayed.
E.g. http://services.aadnc-aandc.gc.ca/geomatics/rest/services/Donnees_Ouvertes-Open_Data/Conseil_Tribal_Tribal_Council/MapServer/0
This problem appears in the 5.2 and the 5.3 version.

Exporting Map with file-based Feature layers in IE10

Investigate feasibility of printing file-based layers.

User Added Layers - Select File dialog does not remember previous path

Ideally when using the select local file dialog, your previous path will be remembered.

Proxy not invoke when importing some ESRI WMS services

Import of ESRI WMS layer through the Add dataset is failing because the viewer attempt to communicate directly through AJAX call in order to obtain the GetCapabilities document instead of forwarding the call to the configured proxy and CORS requests are not enabled on the service endpoint.

Example of ESRI WMS service causing the issue: http://geoappext.nrcan.gc.ca/arcgis/services/MMS/MW_E/MapServer/WMSServer?request=GetCapabilities&service=WMS

GetFeatureInfo is not working with WMS Services for a root layer or a group layer

When we use the Add Dataset Function with a WMS Service, the GetFeatureInfo is not working for a root layer or a group layer.
Sometimes there is a hierarchy in the GetCapablities and the GetFeatureInfo is working only for the leafs.
(e.g. for the service http://maps.geogratis.gc.ca/wms/eab_en?service=wms&version=1.3.0&request=GetCapabilities&layers=emerald_ash_borer_reg_area , the GetFeatureInfo doesn't work for the layer=emerald_ash_borer_reg_area and layer=eab)

Metadata Abstract

Not able to see the abstract metadata when we click on the Metadata in Frencn. The english version is working. See attached images

Export Map not working consistently

Periodically the ArcGIS Online print service takes a long time to respond and request times out, subsequent responses then become more stable. Could also be a result of the AGOL print service having issues accessing hte services it needs to access. Have been able to verify this is working on the RAMP at http://160.106.128.113/ramp/ramp-fr.html with no services added.

Wrong rendering of complex pattern fill on FeatureService

The viewer is not rendering properly some complex pattern fill.

Thematic layers disappear when base map changes in IE

When the base map is changed, thematic layers that were already on the map disappear.

This seems to be specific to IE. It works fine in Chrome.

For reference, I tested this with IE 10.0.32

WMS GetFeatureInfo - Horizontal HTML Results do not fit into results Panel

No scroll bar is available. Not all attributes are in view (e.g. http://services.aadnc-aandc.gc.ca/geomatics/services/Donnees_Ouvertes-Open_Data/Conseil_Tribal_Tribal_Council/MapServer/WMSServer?request=GetCapabilities&service=WMS)

Buttons on Toolbar Disappear in Low Resolutions

When RAMP window is resized to a small width, toolbar buttons begin to disappear as there is not enough horizontal real estate to fit them all.

Hide function

When the layer title is long, the Hide function does not appear.

Loading Label Persists

The loading label in the map window is always displayed even when the loading is done.

When there is an issue with a WMS Layer, every Reload attempt adds it to a list of GetFeatureInfo Requests

When there is a problem with a service, a user is able to reload the layer. When the service is fixed, the layer will appear after the reload but when the user makes a getFeatureInfo request, he will receive as much information as the number of times that he try to reload the layer. For example, if he tried to reload the layer 5 times he will receive 5 answers for a getFeatureInfo.
