These three conferences are influential in my academic GIScience circles. (stalwarts) (1) Conference on Spatial Information Theory; http://www.cosit.info/ (2) International Conference on Geographic Information Science (GIScience); http://www.giscience.org/ (rising in importance) (3) ACM SIGSPATIAL International Conference on Advances in Geographic ...

Don't forget about Geonames dataset: The GeoNames geographical database covers all countries and contains over eight million placenames that are available for download free of charge.

Having spent some time recently talking with teaching staff regarding new GIS students one of the things that most students seem to be lacking is a sound understanding of database theory and data storage and management practices. I realize it is not a glamorous subject, but a good grounding in database theory will go a long way towards reducing errors in ...

I consider these open and ongoing topics in GIScience: implications of user generated content (aka Volunteered Geographic Information Systems) geographic effects on social networks geographic network analysis geographically-enabled agent based modeling spatio-temporal structures and analysis rapid, interactive experimentation (aka geodesign) spatial ...

My perspective is skewed toward the U.S., but both the AAG and AGU conferences heavily feature the bread and butter of GIS: spatial analysis, remote sensing, spatial statistics, cartographic methods, geographic demography and others. at AAG in particular it is a minority of sessions that do not feature GIS (the toolkit), and there are dozens of sessions on ...

That is SonarWave Lite by Tekmap. It's free and can be downloaded from the preceding link if you have some SONAR data lying around that you want to play with. The company who makes it also appears to make heavy use of GRASS and GDAL - so you can consider SonarWave Lite to be GIS-based, but for a very specific application. EDIT: I looked a bit more into ...

Besides GIScience, I would add SDH (Spatial Data Handling conference), GeoComputation and the AGILE conference, in Europe. More focused on cartography, there are also the ICC (International Cartographic Conference) and AutoCarto conference. An excellent resource for GIS conferences traking is this conference calendar maintained by colleagues of the Zurich ...

Absolutely you can. And it can be quite fast. There are several ways, but one way that I've been working with is in using an ordered list of integer-based geohashes, and finding all the nearest neighbour geohash ranges for a specific geohash resolution (the resolution approximates your distance criteria), and then querying those geohash ranges to get a list ...

The GI Forum in Salzburg is well-known and respected, http://www.gi-forum.org/. A publication/presentation at an event like this is a peer-reviewed, competitive event. Same as at COSIT. Much more valued than a presentation at AAG, for example, which has an open call for presentations. Presentations at ESRI's UC are somewhat peer-reviewed, but are not as ...

American Society of Photogrammetry and Remote Sensing (ASPRS): The imaging and geospatial information society. Founded in 1934, the American Society for Photogrammetry and Remote Sensing (ASPRS) is a scientific association serving more than 7,000 professionals worldwide. Our mission is to promote the ethical application of active and passive ...

Natural Earth's Populated Places could be another option.

The question could be read in several ways. I interpret it to mean you have a large number of points and you intend to probe them repeatedly with arbitrary points, given as coordinate pairs, and wish to obtain the n nearest points to the probe, with n fixed beforehand. (In principle, if n will vary, you could set up a data structure for every possible n ...

One issue might be the number of satellites. Some formats - such as NMEA as described here - include a number of satellites record for each point. With that information you could remove points where satellite coverage is poor, as being potentially unreliable. NMEA also includes a Horizontal Dilution of Precision (HDOP) value which you can also use to ...

The GIS Research UK (GISRUK) has been running since 1993. Although with UK in the title it attracts researchers from all over the world. My subjective impression following the papers from last few years is, that the quality and variety of the topics covered is really impressive.

Geohash are very simple and effective way of indexing spatial features, particularly point features. Line and polygon features are little harder to index, but can be done. Geohash is a static hierarchical fixed size grid, overlayed on top of the earth surface. Grid cells of the same hierarchical level do not overlap. R-Tree is a dynamic grid which cell ...

Automatic, yet appropriate, generalisation. Being able to take high order geometry with a lot of detail and simplifying it for a coarser detail map, without dropping important features, is darned difficult. For example a chain of small lakes visible at 1:50,000 should not be shown at all at 1:500,000, yet the watercourse that connects them should remain ...

Some terminology first to set the context: Load balancing is a computer networking methodology to distribute workload across multiple computers wikipedia. Distributed computing instead refers to a network of computers who interact with each other in order to achieve a common goal wikipedia. The difference would be that in load balancing the requests are ...

Automatic geocoding. So far as I know, MetaCarta is the only company talking about or providing a service which attempts to automatically georeference any document based on it's content. For example it knows Mark Twain's Tom Sawyer lives along the Mississippi River. This is a rich field and there is a lot of room for more players and implementations.

You won't find a generally agreed on list; but based on your industry or area of concern you most often will find where most of your peers tend to present. Property Tax/Appraisers have there own associations, as do the e911/NextGen911/NENA crowd. For most used in the USA you will find the Regional/National URISA Conferences, as well as ESRI IUC are major ...

Ian McHarg's Design With Nature is often credited as having laid many of the foundations of GIS. Arguably, Ian McHarg’s 1969 landmark book Design With Nature has had a greater influence on the development and application of Geographic Information Systems than any other single event in GIS history. "McHarg's Method" describes how, thorough and ...

Implicit or suggested topology. wouldn't it be wonderful if the computer noticed that the geometries of layers X,Y & Z were very similar to each other, nearly always following the same trends, and offered to conflate/merge them, or keep the others in lockstep when one is changed?

Big spatial data analytics using open source software for distributed computing such as Hadoop. There is huge potential for processing massive datasets like high density Lidar data in a distributed computing environment. Berkeley Open Infrastructure for Network Computing (BOINC) is currently an open-source platform for distributed computing. ESRI has ...

I have looked through different search results on a good list, and the best I've found so far was: http://www.gsdi.org/upcnf. I have helped organise several GIS-related conferences myself, and have attended several, and since GIS is quite diverse as everybody knows here, it really depends on which crowd you are looking for, being that developers, analysts, ...

Even though there have been already a couple of answers here my thoughts (being now 10 years in the research area). However, just before, I might say that locally there are important conferences - with fewer international participants, due to availability of travel budgets. Also it is probably important in what GIScience application field you work. E.g. if ...

Use of robotics for spatial data collection doesn't seem to be hot - but I think it should be.
