The point at (0°, 0°) is not generally given a name All geographers, cartographers and surveyors ought to know the following, but I reference some sources anyway: According to Matt Rosenberg The point at which the equator (0° latitude) and the prime meridian (0° longitude) intersect has no real significance but it is in the Gulf of Guinea in the ...

It's "there where all the data shows up when something goes wrong". At least that's how I call it, or how I often detect when something went wrong. Others would call it Null Island, which is often used in a humorous way. For an occasional good laugh I would recommend some of the Null Island accounts on Twitter, such as Null Island Gang, Maptime Null Island, ...

Yes, you still reference coordinates (0, 0) as the origin in respect to the coordinate system as a whole. In essence, coordinate systems are grids in themselves. Therefore, terminology between the two are shared. See how ArcGIS refers to the "Grid" location as the origin.

Given that you have exactly seven classes (do they really pick up on Sundays?), and that they're categorical (not quantitative) classes, I'd say that having seven different hues and yet similar intensities and saturation levels is a good way to go. You could probably even squeeze, say, orange and indigo/violet‡ in there, in place of the grays. While ...

Here is a suggestion using ggplot. It can be improved, but it gives you the basic idea. library(maps) library(ggplot2) us.map <- map_data('state') # add PADD zones us.map$PADD[us.map$region %in% c("maine", "vermont", "new hampshire", "massachusetts", "connecticut", "rhode island", "new york", "pennsylvania", "new jersey", ...

The Exception is occurring when time manager tries to parse the date string but finds a unicode character \u017d (a "Ž" symbol) instead. Is your CSV file formatted correctly ?

One possibility underlying the poor kriging performance could be the field plots (location and sampling intensity) failing to capture the spatial autocorrelation (or spatial dependence) in the data. It would be necessary to observe how well the theoretical semivariogram fitted to the data (experimental semivariogram) (Figure 1). If it is the case, one ...

In QGIS 2.8.0 you can do that with the offset option in the Style Layer Properties. In my example with three polylines (they are exactly superposed too): Click in "Simple line" of line2 to display "Offset" option (I set 1 mm): Click in "Simple line" of line5 to display "Offset" option (I set -1 mm): The result obtained (Offset of line4 unchanged; 0 ...

You can use the Merge Divided Roads (Cartography) tool for this. Generates single-line road features in place of matched pairs of divided road lanes. Matched pairs of roads or lanes are merged if they are the same road class, trend generally parallel to one another, and are within the merge distance apart. The road class is specified by the Merge ...

7 colors is not too many. My go-to resource for at least getting a start on a color scheme is ColorBrewer, their tool will allow you to pick the number of data classes you have, the nature of the data (quantitative, qualitative), and a color scheme (dark, pastels, etc), and will give you a preview of how your data will look and the color codes you'd need to ...

It is not clear whether “day of week” has as categorical/nominal or an ordinal scale. Since your colors “follow the rainbow from Monday to Friday” I assume that the order/sequence of the days is important for your application/analysis. Therefore, the following applies only if “day of week” has a ordinal scale in your application/analysis: I am not aware of ...

maintainer of plugin here - seems the CSV is not formatted correctly. It seems there is something wrong with the header line (some extra characters). Also the dates need to be normalized, all the same format and with the proper zero padding. All these have nothing to do with the plugin, it's just input requirements for dates and csvs. However, there were in ...

The aesthetics might look better if you used colors that are more similar to one another, so you wouldn't get such an affront to your eyes. If you look inside national geographic, they often have basemap features in dark grays and blacks, with dividing lines in white, with a single color representing the variable they are showing. Usually a muted red. Using ...

I have search around a little but the only reference I can find to being able to add the factory code as dynamic text is with the Production Mapping - MPS Atlas extension http://resources.arcgis.com/EN/HELP/MAIN/10.2/index.html#//019t0000003z000000
