easy to look at I it doesn't require any additional data those however the head user has to actually look at the data itself they can go back and look at the data itself and tried it if you're
looking for time you'd have to look at the labels 4 you can include colors
and OK so this is also a static Grauman the yeah it's good for a printed publication because it's done in black and white that limitation is the viewer has to interpret time-location just like on other
map and you can see that very well that I'm you can see that there's a rout along there and have to actually get reader labels and see what's going on on and there is also a key associated with this is that there is what's nice about this is that black and white OK so animation
maps Brown the Our I like movies basically you know it's like going and you to clicking playing and watching that's it that's just an animation map but there are some that have controls making the forth which is really nice the this is a track map of
the it's a on being the global age and the colour and this is a movie and the colors denote denoting the temperature and I
after all the say that this was then it's time manager the big limitation with time manager as well as with using Excel for passing is the date limitations of the library that's a huge problem so
basically this is about that goes along the route in late lights up along played
out there right now uh so this is a light rail and line to Portland this is where leaf let and i it's attracting animated so basically this is like if you had a GPS rowdy did go in and get this and you can you know they decided back and forth see where you are over time I'm pretty sure you seen a lot of those over time the
limitations are that Mr. visualization implies that the travel is only 1 1 speed it cannot have variable speed which would be really nice they don't so i'd have to make separate maps for a variable speed so that's what this is that
on the train goes down when the track and then each 1 of these black things is an actual stop and the user can actually click on that location and get information I I
OK so I talked about sliders you're can see that that is the most popular component for a time maps and members innovations are sliders there's J. queries lighter there's these openly and sliders in other from this dojo also has a slider and and this a really good piece of software as well flow complicated but it's very good OK so this
is not at the the network right now but you could include that have reversed in and reversing aligns the rivers are on the map that they're really hard to see and I think if you're going do have fled map or anything having to do with rivers you need to include a separate layer for rivers that's beyond the base map because the base map that you download these are all tile-based maps downplays the reverse so you can
see the water on MAC how light it is what I would think is somehow ones for rivers would make it much better what's nice about this is that it shows the going of you see this top part here it allows you to filter data so that means I can have several different types of data along the string I can have hi floods fled the medium floods this also had includes duration how long the floods last the and then you can Click here to go to more detailed data so you can have things
linked together and as you move across you see things appear and disappear so he had the center lines from there you would see that there I you could actually put this data on the river network itself but
in order to do that you would need to slice the river at these locations from into falling and in that way you can have portion of the river the size that you want it to be it's the they're slicing it in here you actually do need a slice it it's this is very limited data inside of your GIS you would have it as as linear referencing OK few natural linear referencing at some locations along a trail the mile place my points along the string and so you can have an advance from into and you have event tables inside of your GIS to put it in here you have to x 40 doubt OK and then you have to have some put it into a format that's usable inside of these library sees JavaScript libraries and they prefer J. Sun format very so on if you set it up inside of your GIS where you do linear referencing then you kid make some scripts to Click on the day that an expert about into Jason format on the server and have that load up as the same file name over and over again every day and you will need a story that it could just be replaced because you would need to store it because it's still inside a GI GIS OK so 1 other thing this
is time my body that's 1 of the really great thing about time magic about gestures it shows it shows polygons it shows Rastas a hand and it shows pathlines it shows it basically can sell everything it's still days on data but you can show everything so it's a very versatile format and and an 8
ECB that time on that day us would only go inside of openly errors and now there is a way to get it inside of leaflets the so you can get it directly in the leaflets which means you can have all of these datasets
inside a leaflet you can have your path for your outs right inside of leaflets and on use what's really bring about that is that the in lieu of life that you have to the find that really really good at time library it's the best 1 I've seen what
so this is the this is not going to give it a 2nd but kind the so you can
click on the think that information
but the OK so the 2nd half
of library that I found that's really really good in this room leaflet and then time is called human it's data visualisations for them you entertaining data set OK but it's not limited to to that the reason why I think it's really good is because and the
proportional symbols are great then it includes all spark lines but that is is is a graph as a particular point I didn't put that an example on here because he he has to most data if you can include those graphs on a map is study very very few data points for it's gotta be inside the little blob as if it's on the entire period of but what's nice about this is this is a very famous I'm visualization units Napoleon's march right units in a tough but Charles mean not of what's nice about this is from the have another plug-in that allows you to show ends on the ends of life the joke Errol's so you can show flows which means you can have several line layers and you can include a line layer with those bonds to show where the location the flow so that right now we have to actually click on information dots to see when they were the but if you add another layer with more lines the power the outflow and you could color coded by time OK of and so you had this looks like this is a really wonderful library the it goes along you hover over the . any information if you click you get a natural table and this is from the same
library this is F Low manner so it's rasterizer lines why is that important grass tracing lines because you can do this kind of thing you really want to be able to do a diffusion map with such that this is this is a diffusion map showing the location of the runners over time OK and this is home
y to you from different locations and this is also with that From plug-in and what's nice with this 1 is again if you click on a you can get the actual dataset or you hover your mouse and you get get from legend information for each specific spot and then it shows you where it's going to and you can have many different layers under the layer thing up there and that's what I would recommend is many different layers to get your point across you know 1 layer for the planes 1 layer for the routs another later perhaps for and if you're trying to show trying in a specific way and
this is the this is the beetle map with
open and my implementation where most of these it is that these sliders I'm not that smart they're stupid if you don't sort your data it will not appear in the correct order so you need to sort the data In that when actually has
a a search so you can search but it has to be in that time format that you can if you re write up JavaScript function that allows the user to picture like a time format from a calendar from and like sliders you know it would be much better because the time format is horrible and most of these really really horrible yeah I know it's time OK
OK so I'll just finish up with this 1 this 1 is open my again this is a movie in letter that the in the that and that case the paragraph flat in that I have when it all in 1 of the that kind of thing so we get that the better the so I'll stop there and for any questions I think you

Abstract Maps are traditional means of presentation and tools for analysis of spatial information. The power of maps can be also put into service in analysis of spatio-temporal data, i.e. data about phenomena that change with time. Exploration of such data requires highly interactive and dynamic maps. Using geospatial open source software, various techniques for visualizing spatial temporal network change data and combinations of spatial temporal network, point and area data are evaluated. Linear referencing represents locations along routes, linear features with an established measurement system, using relative positions. It allows locating events along routes without segmenting it, and has been applied to manage linear features in transportation, utilities, along trail networks and stream networks. Linear referencing for events occurring along a network through time are visualized using both animations and interactive time line visualizations. Sliders are used to give the user manual control to step through the data, allowing them to explore the data presented in each time step. Categorized point events (i.e. traffic accident types, flood locations, etc.) appear at muItiple locations along the network. Color and size of symbols are used to denote these dynamic point event attribute changes and location changes. In addition, line segments are mapped using size and color to identify the changes occurring over time. Some of the combinations of changes evaluated include: attribute change (i.e. traffic accident type), spatial attribute change (i.e. flood boundaries), moving objects (i.e. traffic accidents), rate of change (i.e. fish survival by stream segment) and spatio-temporal aggregation (i.e. multiple fish releases by watershed). Some linear visualization techniques evaluated include: run maps and map and line chart visualization techniques similar to the famous Napoleon's retreat Minard visualization.
