Collector para ArcGIS e gps externo

RobertHarris5

<\/HEAD>

Com a versão 10.4 lançada, agora podemos ver a precisão espacial do gps no Collector no iOS. Tentamos conectar algumas unidades de gps externas ao dispositivo para ver se conseguimos melhorar a qualidade do gps. Após conectar o dispositivo externo via bluetooth e configurar o Collector para reconhecer o dispositivo, toda a capacidade de usar o gps para de funcionar no aplicativo. (a janela de precisão desaparece e o botão de alternância do gps no mapa fica desativado) Ao desconectar a unidade GPS externa, a capacidade do gps volta. Alguém já passou por isso? Alguma sugestão de como resolver? Alguém teve sucesso com alguma unidade Trimble?<\/P>

Follow up on this topic for anyone interested. Pairing certain low accuracy external gps devices (tested the Garmin Glo) can be done simply by connecting via bluetooth without configuring the connection in Collector. We then attempted to connect a Trimble Pro6H with NMEA and Floodlight activated. We had to purchase the AMAN enterprises NMEA-BT unit to send the gps stream to Collector. You then have to download an app called NMEA Talker and configure it. After that go through the Collector settings menu to change the provider and configure your Location Profile. This worked very well for us. We tied into a local RTK subscription service and were able to see better than submeter quality data. Two downsides, one is that Collector does not seem to like to report better than 12.3' of horizontal accuracy. We have to perform more testing to quantify this. Second was with the Pro6H unit itself. We found out that upon powering the Trimble unit down, the NMEA output is toggled off. So if an end user planned to use it for the day, they would have to connect the Trimble unit to their desktop and enable the NMEA string again. This is an inconvenience for now, but limits our end users to qualified GPS/GIS field crew members.

Hi Robert,

I face the same problem with you when I try to use GLO with Collector 10.4 for iOS. Do you have any workaround on this ?

Thanks,

After working with ESRI support on this, the Garmin Glo works out of the box with Collector, no configuration within the app is required. Just connect the device via Blutooth and open Collector. Because of the data stream the Glo puts out, any further configuration with the Glo will not work. (The Glo is NOT a high accuracy GPS device) Here is the response I received from ESRI regarding the GNSS badge within Collector:

"Here is the answer to your question; When using the Integrated Receiver on iOS devices, regardless if the accuracy is coming from an external GPS receiver, its limited to only reporting up to 5 meters. Therefore, the GNSS badge in Collector will only display accuracy up to 5m or the equivalent in feet.

Additionally, you will not be able to utilize any of the advance high-accuracy gps capabilities with the Garmin Glo in Collector because it will use the Integrated Receiver on iOS to connect with Collector. For example :You will not be able to use location profiles(required for collecting data in a projection that is not in Web mercator) and be able to collect any of the GPS metadata."

Here is a link for connecting to high accuracy devices: Use high accuracy GPS—Collector for ArcGIS | ArcGIS

Robert,

I've been using an iPad with Arrow 100 GNSS receiver (Apple certified) and have had no problems with the receiver passing info to Collector. We also are able to connect to our state department of transportation's RTK service after setting up the profile. Everything has worked fairly well so far.

Anyone had any luck with Carlson external gps units? Please help!!
They are hemisphere based.

I don't sorry. We are using the Trimble R2 with a paid subscription that has been working well. We had tried the Eos Arrow and that worked well also.
