Rest dynamic map service service does not display in Tax Parcel Viewer 10.1

davidwray

The following Rest service does not display as a operational layer when isVisible = false

http://arcgisweb.roanokecountyva.gov/arcgisweb/rest/services/Z2/MapServer/0

When I change isVisible = true the service will display, but I cannot toggle on and off.

Any ideas?

David -

I would contact Esri Support Services to get help with this specific issue. They can help you troubleshoot the issue more deeply.

One quick check - I would assume you're trying to add the parcels as a dynamic service in the operational layers area of the config?And I assume you're service is in the same projection as your basemaps, etc.?

Hi Scott,

I contacted Tech support and the answer I got was a bug in the code. Yes, you are correct and I am
trying to add Zoning as an operational layer in the config file and it is in the same projection. In my
opinion the problem is with the complexity of the symbology in the map service.

Very unfortunate,
David

Hi David,

Thank you for the information and the URL of the service that you were using. We did have a bug that prevented a layer that didn't have a symbol renderer from appearing in the basemap switcher box. Without the checkbox in the switcher, you can't change the visibility from the user interface.

This has been fixed in the latest version of the Tax Parcel Viewer in Esri's github site: a default symbol is provided for the layer.

Thanks,
Mike

Thanks Mike! The Layer adds to the map perfectly. One last question, my map service, please see below is transparent, but
when I add it to the map the service is not transparent. Any ideas on how I can solve this problem?

Hi David,

You can get this by adding a line to the js/utils.js file; where you see the lines

function CreateDynamicServiceLayer(layerURL, layerIndex, layerId, isVisible, displayName) {
    var imageParams = new esri.layers.ImageParameters();
    var lastindex = layerURL.lastIndexOf('/');
    imageParams.layerIds = [layerIndex];
    imageParams.layerOption = esri.layers.ImageParameters.LAYER_OPTION_SHOW;
    imageParams.format = "jpeg";
    var dynamicLayer = layerURL.substring(0, lastindex);
    var dynamicMapService = new esri.layers.ArcGISDynamicMapServiceLayer(dynamicLayer, {
        id: layerId,
        imageParameters: imageParams,
        visible: isVisible
    });
    var initiallyVisible = isVisible;

insert the highlighted line to have your map service send the JPEG format instead of the default PNG8.

Hi Mike,

I am trying to use the Tax Parcel Viewer as a School Finder for the Police Department and I need to use Secure Rest Services. Does the tax parcel viewer support using token based security? If so is there any documentation on how to configure the app? It has proxy.cfg and proxy.ashx files in the application folder so it would seem to be fairly easy to configure if the Tax Parcel App will support it. Thanks for your help!

David

MikeTschudi

Hi David,

The proxy.* files in Tax Parcel Viewer just support cross-domain access--they don't have token support. If the secure REST services are on ArcGIS.com, I'd recommend the proxy.* from Esri's map-and-app-gallery app (see this post) along with a modification to the Tax Parcel Viewer to set esriConfig.defaults.io.alwaysUseProxy to true in js\homePage.js. (Note that we just released a new version of Tax Parcel Viewer to Esri's GitHub site.) This version of proxy.ashx requires that all of the query services need to have the same URL prefix , e.g., "http://www.arcgis.com/sharing/", but the program can be modified. There may be some additional tweaking to the app for the secure URLs, but I think that it's doable. If the secure REST services are hosted elsewhere, then some custom modifications may be necessary to the proxy.ashx program to adhere to that server's token rules.

Rather than use Tax Parcel Viewer, have you considered adapting Park and Recreation Finder? I mention it because it's been a popular base for custom finders.

Regards,
Mike

Hi Mike,

I currently have the Tax Parcel Viewer 10.1 working with Secure Rest Services and dynamically
generated tokens using ESRI proxy files. Since reading your post I downloaded the 10.2 version
from GITHUB and have installed on my test server. The app will Load and will query and return
results in the search window but when i click or select one record to zoom-to, the app will fail to
load and will continue loading. I have made the app publicly available here:
http://picolsvr.roanokecountyva.gov/taxmaster102a/

and the app with Roanoke County data is located here:
http://picolsvr.roanokecountyva.gov/taxmaster102/

Any ideas on the problem and a solution?
The AutoComplete is a really nice new feature and it works well.
Once this problem is resolved would it be possible to use the proxy files that I was using with
version 10.1 with v.10.2?

If not, what is needed to get the app working with Secure Rest Services on a local ArcGIS Server?

I have seen the Parks and Rec Finder and it is a nice app. I plan on deploying that App on our site
in the future but we are currently collecting data to use in the App.

Does the App support Mobile devices?
Are their plans to add Autocomplete functionality to the App?

I plan to add the Schools to the app and see how well it works.

Thanks for all that you and the Local Gov't Team do to make GIS successful at the local level.

All the Best,
David

Hi David,

Both sites are getting stuck by a flaw in the app that's preventing the selected parcel's popup from appearing. Please change line 686 in js\locator.js from

dijit.byId("divProperty").select();

dijit.byId("divProperty").selected = true;

I've made this change to the github version.

The ArcGIS authentication that the proxy uses has not changed from 10.1 to 10.2, so you can continue to use that proxy program.

The current version of Parks and Rec Finder supports mobile devices and has autocomplete. It will be available in the upcoming 10.2 release, or you can get it now from the Esri GitHub site (https://github.com/Esri/park-and-recreation-finder). (However, as with the other almost-10.2 apps in our GitHub site, such as tax-parcel-viewer, it is undergoing testing right now. When the repository commit is tagged with "10.2", you'll have the version that goes into arcgis.com and will be supported.)

Regards,
Mike

davidwray

Thanks Mike! It works great now. I found that the App did not Zoom-In to the parcel so I modified the following code. Please see
below:

Utils.js line 115 before:

//Get the extent based on the mappoint
function GetBrowserMapExtent(mapPoint) {
    var extent = map.extent;
    var width = extent.getWidth();
    var height = extent.getHeight();
    var xmin = mapPoint.x - ((2 * width) / 2.8);
    var ymin = mapPoint.y - (height / 4);
    var xmax = xmin + width;
    var ymax = ymin + height;
    return new esri.geometry.Extent(xmin, ymin, xmax, ymax, map.spatialReference);
}

Utils.js line 115 after:

function GetBrowserMapExtent(mapPoint) {
// Added code to Zoom to selected Parcel
    var extent;
    if (map.getLayer(tempParcelLayerId).graphics.length > 0) {
        extent = map.getLayer(tempParcelLayerId).graphics[0].geometry.getExtent().expand(6);
    }
    else {
        extent = map.extent;
    }
    var width = extent.getWidth();
    var height = extent.getHeight();
    var xmin = mapPoint.x - ((2 * width) / 2.8);
    var ymin = mapPoint.y - (height / 4);
    var xmax = xmin + width;
    var ymax = ymin + height;
    return new esri.geometry.Extent(xmin, ymin, xmax, ymax, map.spatialReference);
}

Thanks, David--I've added your enhancement to Esri's GitHub site.

Mike,

i have added 3 operational layers to the TPV (Residential Sales, Commercial Sales and Land Sales). Only 2 of the operational layers show up in the legend. can you duplicate this error with the 10.2 version from GITHUB? I can add a 4th operational layer and 3
of the 4 layers will show up in the legend. Also, if I only have 2 operational layers in my config.js file both layers need to be
checked in order to perform the identify function.

I have attached the config.js file that I am using for your review. Is this a bug or am I missing something?

Thanks,
David

I tried attaching the config.js file, but it was too large to upload. Below is the code snippet of the operational layers configuration from the config.js file. is anyone else experienciong a problem with the operational layers?

    // Layer data is shown in the info window for parcel,sales and foreclosures.
    // Key is used as an layerId while adding this layer to the map and has to be unique
    // Title will set the layer name of the infowindow
    // ServiceUrl is the mapservice URL for the layer
    // isVisible is the boolean parameter to check if the layer is a currently visible or not
    // isDynamicMapService is the boolean parameter to check if the layer is a dynamic map service or not

Hi David,

You've found some interesting issues, but I cannot determine the causes yet.

Missing legend items: I've narrowed it down to an operational layer claiming to not have a symbol even though the symbol has been clearly transmitted over the network as part of the layer. In the version of the software that you're using, that missing symbol prevents the layer from appearing in the legend and the symbols from appearing on the map. Especially odd is that, if I configure the app to have multiple copies of a service, it's possible for one copy to have a symbol and the other to be missing one.

Identify problem: I can reproduce it easily using your services.

I also see that the latest version of the software does not gracefully handle layer names long enough to wrap onto a second line.

I don't have solutions for you yet, but I wanted to let you know that I've been working on it. Your configuration has been extremely useful--thank you for supplying it.

Regards,
Mike

davidwray

Mike,

Thanks for the update. Also, I am unable to perform the identify function when I have only the first layer in the legend checked. If I check the 2nd or 3rd layer in the legend the identify functionality is enabled. Are you able to reproduce this issue? If so, do you think it is related to the symbology passing thru the service? Please let me know if I can be of any assistance.

All the Best,
David

MikeTschudi

Hi David,

My very-short "Identify problem" stood for a bunch of problems with identify, including the one that you mentioned. 😞

You've been very helpful by pointing out the problem and providing the services--the challenges so far have been to figure out what's happening; the next challenges are to figure out how to solve them!

Thanks,
Mike

davidwray

Hi Mike,

I thought I would check on the status of the identify issue. Any updates?

All the Best,
David

MikeTschudi

Hi David,

Progress has been stalled due to both technical challenges and time assignments, but I very much want to solve this one.

Regards,
Mike

JayGeisen

David,

I sent you a PM, but not sure you will see it so I'll post here too.

How were you able to add a dynamic service to the application? I've tried everything I can think of, but I can't get anything to display. Would you mind posting your config file, please? Ideally, I'd like to be able to add a dynamic service that doesn't appear in the basemaps list.

Thanks,
Jay

JayGeisen

Actually, you can disregard my question as I've figured it out. Thanks
