There were no “hard” specifications, when we spoke early, this fall. I provided them with some of the requirements, as I saw it, from a stte DOT perspective. The foundation of this was providing a state DOT with the opportunity to expose their LRS for public use and allow “external” as well as “internal” users the ability to crept point and linear events that could be exported as feature classes. Getting feature classes out of AGO will become complicated. HOWEVER… “Simple” linear referencing is a thing of the past. Users will need to incorporate temporal concepts into their event tables and LRM results. Additionally, AGO/Portal will need to enforce this. Temporal concepts for the LRS and the events will need to be understood by desktop and online users, alike. This is more complicated than locating tables of X,y values or geocoding addresses. The details that we commonly ignore with respect to these processes cannot be ignored when implementing an LRS solution. The results could be disastrous. Users will need to be better trained and informed on the proper use of LRS data. Jim James E. Mitchell, Ph. D.

Gavin, First, do have this in ArcGISIdeas and votes for that subject help move these things along. The ESRI developer expressed some concern that if AGO/Portal support LRS, that ESRI would have to provide some sort of route reference system . They recognize the impracticability of that; an “LRS for the whole world.” However, that is not the point. Organizations who want to have online LRS capabilities already have an LRS and want to use that. Some generic LRS is of no use to them. Thai want to share their LRS within and outside of the organization to promote interoperability across systems and organizations. They want people to be able to “Locate Features” on their LRS and create GIS features that can be further analyzed or visualized. Specifically, they want the capability to work with linear events, not just pints . We are all looking forward to these developments. Jim James E. Mitchell, Ph. D.

Gavin, I have been working with AGO developers on this topic. This is a key point have tried to make. LRS support requires a route reference system, but does not require it to reside on a server or from a service URL. The approach I have tried to promote has several options: 1. Tread LRS the same way as Address Locators – provide the ability to specify a service that is available to all AGO Organization or Portal members . 2. Allow the AGO user to upload or access AGO content that is a polyline_m feature class – use this as the route reference. 3. Preferably both of the above. Users who have Event Tables should be able to access a route reference system and do LRS, just like in ArcMap. AGO developers tell me they are working on a prototype for Q1 in 2019. We’ll see… Thanks, Jim James E. Mitchell, Ph. D.

Getting linear referencing into AGO will really open-up access to our enterprise and legacy data for lots of new users. ... View more
