    Ed Parsons discusses the concept of Spatial Data Infrastructures (SDIs), emphasizing the importance of sharing geospatial information with a wider audience. He critiques traditional SDIs for being developed by professional data publishers and agencies, which may restrict accessibility to a broader community. Parsons highlights that while progress has been made in publishing content online, there is still work to be done in making this data truly accessible and user-friendly, particularly by adopting standards and improving licensing policies.

    The focus then shifts to the importance of user-centric design in application development. Parsons draws parallels between the consumer app market and SDIs, advocating for a user-focused approach in developing geospatial applications. He suggests that SDIs often contain excessive complexity and that developers should simplify the underlying infrastructure while maintaining a focus on user needs. He concludes by stressing the need for good web citizenship, promoting the idea that merely creating SDIs isn't enough; they must also be effectively marketed and supported to ensure they meet the needs of users.

    Insights 2015: By Ed Parsons - Topic "Making SDIs Work" - Recorded at GeoQuest2015
  • 00:00:06
    My name is Ed Parsons. I'm Google's geospatial technologist.
  • 00:00:09
    I think the the principal, the concept behind Spatial Data Infrastructures
  • 00:00:13
    is a good one
  • 00:00:14
    Clearly no one would argue that sharing
  • 00:00:17
    geospatial information with a broadest community possible
  • 00:00:21
    is a good idea. I think part of the problem
  • 00:00:25
    is historic. The SDI's have largely been developed by
  • 00:00:29
    traditional data publishers, mapping agencies
  • 00:00:32
    Cadastral agencies, used to serving a
  • 00:00:36
    professional market in a particular way.
  • 00:00:39
    And, I think as a result of that in the SDI's that you see around the world at
  • 00:00:43
    local, regional
  • 00:00:45
    national, even at a global scale, have
  • 00:00:49
    developed on technology platforms that requires specialised
  • 00:00:53
    and just do geospatial. And, as a result of that I think they have missed
  • 00:00:57
    many the opportunities, that the broader web,
  • 00:01:00
    which is more standardised, more widely used, brings.
  • 00:01:04
    And as a result, I think often the content
  • 00:01:07
    that is published by SDI's, remains invisible to the broader community web users.
  • 00:01:13
    I think usability
  • 00:01:15
    on the web ultimately comes down to a question accessibility.
  • 00:01:19
    How accessible could you make your information. And there's a
  • 00:01:22
    technology element to that.
  • 00:01:24
    And that's about being a good web citizen, making sure that you publish
  • 00:01:28
    your content on the web,
  • 00:01:29
    that is accessible via a web browsers via a URL or a URI.
  • 00:01:33
    And then obviously, there are the policy issues as well.
  • 00:01:38
    And that's more towards Open Data policies,
  • 00:01:41
    making sure licensing is is brought and is easily accessible.
  • 00:01:45
    And on both of those aspects, I think SDI's have gone quite a long way.
  • 00:01:50
    But, its 80% of to the job done. There's another
  • 00:01:53
    20% that is about making the data
  • 00:01:57
    web accessible, being good web citizens. And I think still probably some work to
  • 00:02:02
    do around
  • 00:02:03
    licensing, with the recognition that the end uses
  • 00:02:06
    aren't necessary going to be someone that you know. Lot of the
  • 00:02:10
    the success of the modern App Market,
  • 00:02:14
    is built on the APIs and programming platforms,
  • 00:02:19
    where a developer has quite a loose connection to the platform.
  • 00:02:23
    Developer may not be aware of whose building
  • 00:02:29
    applications and what their
  • 00:02:30
    end user of those applications are doing. And I think that's something that many
  • 00:02:35
    traditional mapping agencies and government agencies are
  • 00:02:39
    uncertain about. They want to know who their end user is, and sometimes
  • 00:02:43
    for valid reasons. But that's kind of a counter to the way the apps are
  • 00:02:48
    develop these days..... Security is a complex issue
  • 00:02:51
    I and not specifically going to talk about Google.
  • 00:02:55
    Technology on the web is about, you choosing to share information
  • 00:02:59
    with how you want to share it with,
  • 00:03:02
    and not sharing it with any one else. you And that I think now a days means
  • 00:03:06
    that
  • 00:03:07
    most of the services that you use, data will be
  • 00:03:11
    encrypted, when it is REST, as we say as a service somewhere.
  • 00:03:15
    And it will be included in transit, say when is moving from one server to
  • 00:03:18
    another server,
  • 00:03:19
    it will be encrypted. And modern encryption is very very strong.
  • 00:03:23
    Its almost impossible to break
  • 00:03:26
    modern encryption, that's widely used.
  • 00:03:30
    In any said a reasonable period of time,
  • 00:03:33
    if the data is encrypted, and the
  • 00:03:36
    organisation is hosting your data, they are doing agood job. You should be
  • 00:03:41
    reasonably sure that your data is secure. But I think
  • 00:03:45
    in terms of SDI, may be there is still a fundamental question
  • 00:03:48
    the people need to answer is
  • 00:03:50
    do I really want to share my data? And by share
  • 00:03:53
    actually does mean its available to anyone, to reuse it,
  • 00:03:58
    remix it,
  • 00:03:59
    combine it with something else. Because once your data is
  • 00:04:03
    out on the internet, you're sharing, it's a bit like Mercury. It will flow in
  • 00:04:08
    whichever direction it chooses to flow.
  • 00:04:10
    And once its out there, you can't really stop that.
  • 00:04:13
    So in case if I've chosen to share data, it will be shared.
  • 00:04:17
    If I choose not to share data, its encrypted, no really gets access to it.
  • 00:04:22
    I think in many ways you could argue that, the consumer
  • 00:04:26
    market is trying to do simple things. In many cases the data that traditional
  • 00:04:31
    SDIs are dealing with is much more complicated,
  • 00:04:34
    have much richer data models and so on. But I think,
  • 00:04:37
    what we can take from the consumer market is is a very
  • 00:04:40
    strong focus on the user. They are very
  • 00:04:43
    focused on what are the actual user needs for a particular application.
  • 00:04:48
    How do we measure those? How do we see how well we meeting those needs?
  • 00:04:53
    How can we monitor if those needs are changing? And I think those people that are
  • 00:04:57
    developing Apps today, be it on the web or in mobile devices
  • 00:05:01
    have that very strong focus. In that you see
  • 00:05:04
    releases of mapping apps and mobile phones happening
  • 00:05:09
    every two or three weeks or every month with
  • 00:05:12
    developments, changes and most of those developments and changes are based on
  • 00:05:17
    their feedback of
  • 00:05:18
    monitoring how people are using applications, what's working, what's not working.
  • 00:05:22
    That user focus I think is really powerful, really valuable.
  • 00:05:26
    And it's something that developers of SDIs, focused maybe more
  • 00:05:31
    government users could take on board. I mean this questions is an easy one
  • 00:05:36
    ...
  • 00:05:36
    interesting one. I mean, everyone has constraints. Even,
  • 00:05:41
    large commercial companies have to pick and choose
  • 00:05:45
    how they invest their time and capital in building new services, new
  • 00:05:48
    applications.
  • 00:05:49
    There is probably more flexibility if you have a community users thats
  • 00:05:54
    paying license fees or you're supporting
  • 00:05:58
    your services by advertising. Which is what Google does.
  • 00:06:01
    So, perhaps there's a bit more flexibility there.
  • 00:06:05
    But I think, there's a more fundamental
  • 00:06:08
    question. Which is, what do we expect in infrastructure to provide?
  • 00:06:12
    And often we throw too much functionality,
  • 00:06:16
    too much complexity in to an infrastructure.
  • 00:06:19
    In my talk at GeoQuest 2015, someone asked a question about
  • 00:06:23
    the balance between, what goes into the infrastructure
  • 00:06:28
    and what goes into the applications that sit above that. If you look at, you know the
  • 00:06:31
    the really popular apps on your mobile phone - the Google Maps, the
  • 00:06:35
    Facebook..
  • 00:06:36
    Instagram, their applications sit on top of a relatively
  • 00:06:41
    basic Internet infrastructure. Behind all those apps,
  • 00:06:45
    there are web service and traffic that is moving over HTTP.
  • 00:06:49
    You don't see that! That's invisible to you. And compared to the complexity of
  • 00:06:54
    application, that that traffic is quite simple.
  • 00:06:57
    Perhaps in SDI I terms, we've thrown too much into the infrastructure.
  • 00:07:02
    We cam maybe, back-off a little bit and say, this is in a very simple level just
  • 00:07:06
    about
  • 00:07:06
    sharing data on a website somewhere, and we let more of that complexity to happen in the
  • 00:07:11
    applications.
  • 00:07:12
    Which are by their nature, more focused on vertical markets around particular user needs.
  • 00:07:18
    I think so, it's only Web GIS that solved
  • 00:07:22
    problems. So big issues in terms of publishing data.
  • 00:07:26
    And..
  • 00:07:28
    in some ways maybe, you can think of your Web GIS is the obvious application
  • 00:07:32
    that sits on top of an SDI.
  • 00:07:34
    And don't bring, web mapping into SDI itself, but think of it that sits
  • 00:07:40
    on top of an SDI.
  • 00:07:41
    And the SDIs is much more at this very basic level, saying
  • 00:07:45
    at this particular URI, you will always find information about this particular
  • 00:07:50
    land parcel.
  • 00:07:50
    And that means, that data is always accessible to people,
  • 00:07:54
    is consistently accessible, and then its
  • 00:07:58
    in a format that an application developer, another agency can build
  • 00:08:03
    on top, with that reassurance that the underlying infrastructure is not going
  • 00:08:06
    to change.
  • 00:08:07
    I think first of all be good web citizens. And as I said that's about
  • 00:08:12
    publishing all your content by default on the web,
  • 00:08:15
    using as simple tools as possible you know. Using HTML,
  • 00:08:19
    using SVG, using the language is that the rest of the web
  • 00:08:25
    use.
  • 00:08:28
    And looking at the emerging fields of Semantic Web and Linked
  • 00:08:34
    data.
  • 00:08:34
    Because above and beyond publishing your data, to the next step
  • 00:08:38
    is to publish your data in a semantically rich
  • 00:08:42
    way, that makes it easier for people then to build applications. Say that
  • 00:08:46
    if you talk about a highway, and someone else talks about a motorway, we
  • 00:08:51
    know you were talking about the same thing.
  • 00:08:53
    That's the next step. And I think the third step
  • 00:08:56
    is to build an ecosystem that works, support that ecosystem
  • 00:09:02
    Say, I know that I've built my infrastructure that people won't necessarily come and use it,
  • 00:09:07
    unless I advertise, I support, I market
  • 00:09:11
    what I've built. You know there is a famous film quote today "If you build
  • 00:09:15
    it they will come!"
  • 00:09:17
    But actually that doesn't work! If you build it, nobody comes unless you tell
  • 00:09:20
    them.
  • 00:09:21
    So be a good web citizen, invest and look at the Semantic Web and then
  • 00:09:26
    foster the ecosystem around the infrastructure you have built. I think ..
  • 00:09:31
    Geo Portals are great, and they meet the needs of a particular community of
  • 00:09:35
    users.
  • 00:09:35
    But reality is, if you really want to meet
  • 00:09:40
    needs of some specialist vertical markets,
  • 00:09:43
    or particularly easy communities, most government agencies
  • 00:09:48
    indeed many commercial organisations, don't have the bandwidth and don't have
  • 00:09:52
    the expertise.
  • 00:09:53
    Those people that are smart build an infrastructure,
  • 00:09:57
    the allows an ecosystem to exist around that,
  • 00:10:00
    and allows application developers to go down a particular route, plug
  • 00:10:05
    into that infrastructure and build an application that is
  • 00:10:07
    very focused on particular using needs a particular market requirements.
