"Here be dragons" The phrase "Here Be Dragons" (or hic sunt dracones) appears on maps such as the Lenox Globe (from early 1500s) and is now considered to be map shorthand for Here Be Other Stuff We Don't Quite Know About, rather than a claim to have seen a fire-breathing monster. Usually placed to fill whitespace (un-known uncharted lands or seas) on ...
Let's start with: "Everything is related to everything else, but near things are more related than distant things" Known as "the first law of geography" (Tobler W., (1970) "A computer movie simulating urban growth in the Detroit region". Economic Geography, 46(2): 234-240)
"GIS technology is kind of like Google Earth, but beeetter." Arnold Schwarzenegger
I always thought there was a cartographic streak in the writers of the TV show Blackadder. As the Elizabethan Blackadder is preparing to sail around the world he's told: The foremost cartographers of the land have prepared this for you; it's a map of the area that you'll be traversing. [Blackadder opens it up and sees it is blank] -They'll be ...
“There is no such thing as information overload, only bad design.” –Edward Tufte
Geography is just physics slowed down, with a couple of trees stuck in it. — Terry Pratchett
A number of astronauts, and then all of us who saw the photography from space, marveled at how much the Florida peninsula, meandering Mississippi, the islands of Britain, and the boot of Italy resembled the maps everyone had grown up with. We had taken it for granted that maps were faithful reflections of reality; but we were somehow ...
“I am told there are people who do not care for maps, and I find it hard to believe.” —Robert Louis Stevenson, Treasure Island
“The early days of GIS were very lonely. No-one knew what it meant.” –Roger Tomlinson
Question: Why can fish measure distances so well? Answer: Because they have their own scales.
Start here: http://www.qgis.org/en/about-qgis/faq.html Q: I want to cite Quantum GIS in my thesis. What is the correct citation reference of the Quantum GIS project A: To cite QGIS software in your piece of work, for work or an assignment, this general citation might be helpful: "Quantum GIS Development Team (YEAR). Quantum GIS Geographic ...
“If you want a database that has everything, you’ve got it. It’s out there. It’s called reality.” –Scott Morehouse, Director of Software Development, ESRI I have rephrased this quote and often use it as: “If you want a map that has everything, you’ve got it. It’s out there. It’s called Earth.”
Spatial Statistics is probably classic example here. Also Spatial Data Analysis offers solid overview Statistical Methods for Spatial Data Analysis, Geospatial Analysis - a comprehensive guide and Geographic Information Analysis will give you nice overview as well. Another, more practical oriented way to go would be to look at R. Have a look at CRAN ...
The map is not the territory. - Alfred Korzybski
"Can you squish it and rotate it? ... I don't think our [commercial] lot looks big enough on the map, can you make it larger?"
“Maps are like campfires – everyone gathers around them, because they allow people to understand complex issues at a glance, and find agreement about how to help the land.” – Sonoma Ecology Center, GIS/IS Program Web Site
Good question. While http://gpgpu.org is a good resource, it is quite general (the first G stands for General, after all). Searching there for GIS I get only one hit from 2004, which links to a paper that is 404. Manifold is the only vendor I'm aware of leveraging the GPU for GIS. Hoopoe sure looks interesting, which also administers CUDA.NET.
From Sylvie and Bruno Concluded by Lewis Carroll (1893): "We actually made a map of the country, on the scale of a mile to the mile!” “Have you used it much?” I enquired. “It has never been spread out, yet,” said Mein Herr: “the farmers objected: they said it would cover the whole country, and shut out the sunlight! So we now use the country ...
"I want anyone who has never used command-line Arc... ...to leave the room right now." Hitler
One of mine - and I'd appreciate it if someone tell me who to attribute it to is this: "Data quality improves with time and distance from the source" Something to keep in mind when dealing with GIS data. I'd originally heard it from a member of the League of Real Surveyors. Best characterized by this cartoon.
Everything happens somewhere.
Geography has been described as the Los Angeles among academic disciplines because it spreads over a very wide area, merges with its neighbours, and we have a hard time finding the central business area. Pattison and Natoli
How about the appearance of the (fictional) 'Organization of Cartographers for Social Equality' in Season 2 of West Wing? (link to a 4 min clip on you tube) They lobby for the replacement of Mercator Projection maps in schools with Peters Projection maps. JOSH ...you’re telling me that Germany isn’t where we think it is? FALLOW Nothing’s where you ...
Part of the ESRI Applications Prototype Lab's DevSummit presentation was on GPU for GIS. The video link appears to be borked, but a lengthy blog post contains a good summary and introduction to GPU computing wrt GIS. Also, Azavea (formerly Avencia) has won some NSF grants to investigate this area further, and they have a series of blog posts that appear ...
"The last thing you think of and the first thing you need, a map." I read it years ago, I think by a USA Colonel but cannot find the original to cerdit him with it
This paper: Christophe & Ruas 2002, Detecting Building Alignments for Generalisation Purposes, ISPRS, Ottawa. describes an operational method for the detection of small surfaces (buildings) alignements - it should work even better with points! (this method is rather robust since it is used for the production of 1:25000 maps in France).
I've been using Manifold GIS for years, and though at times a target of derision for a variety of reasons, the software is quite impressive. The current version (8.0.18 at time of writing) uses CUDA to accelerate surface operations 100x or so. The long awaited version 9 promises to both improve on that level of acceleration and to broaden the scope of its ...
"The application of GIS is limited only by the imagination of those who use it". Jack Dangermond
I like: "one would have to be singularly unimaginative to experience no excitement when confronted with a map, not least a map of unfamiliar territory studded with exotic names" by Cordelia Oliver, 1989 And the stat of this one has been mentioned but I thought I'd post the fuller version: "I am told there are people who do not care for maps, and find ...
