In this project-based course, you will design and execute a complete GIS-based analysis – from identifying a concept, question or issue you wish to develop, all the way to final data products and maps that you can add to your portfolio. Your completed project will demonstrate your mastery of the content in the GIS Specialization and is broken up into four phases: Milestone 1: Project Proposal - Conceptualize and design your project in the abstract, and write a short proposal that includes the project description, expected data needs, timeline, and how you expect to complete it. Milestone 2: Workflow Design - Develop the analysis workflow for your project, which will typically involve creating at least one core algorithm for processing your data. The model need not be complex or complicated, but it should allow you to analyze spatial data for a new output or to create a new analytical map of some type. Milestone 3: Data Analysis – Obtain and preprocess data, run it through your models or other workflows in order to get your rough data products, and begin creating your final map products and/or analysis. Milestone 4: Web and Print Map Creation – Complete your project by submitting usable and attractive maps and your data and algorithm for peer review and feedback.

Milestone 4: Creating Your Maps

In this module, you will have weeks 7 and 8 to hone your map-making skills, building at least two maps that visually interpret the results of your analysis. In making both a web map and a print-layout map, as well as through extra practice materials, you'll refine cartographic techniques that you previously learned as well as new ones to help you to better display information in map form. Should you choose to, you will also build a small website for your project by the time you complete this module.

Hello again, and welcome to the final milestone in your project.

Now that you've completed the analysis of your data,

it's time to turn it into a format that's presentable to others.

While we separated it from the interpretation of the data that you

submitted in the last milestone, in reality, if you were to make a full

report of your findings, you might want to merge these two steps so

that you can better write about what your maps and figures demonstrate.

In this case, we chose to separate them so you could focus first on analysis and

then on cartography.

Now, you'll make at least two maps for this milestone.

One web map and one traditional print layout map saved as a PDF

the web map doesn't need to be fancy or complicated, but

it should show some portion of your data or conclusions.

The web map is largely so you have a readily shareable version

of your analysis online as part of your portfolio.

So even though we won't put too many requirements on what should be included in

it, spend some time with it to make it tell the story you think your data has so

that you can share the map and show your capabilities as an analyst.

The other map you'll make is a traditional print map.

At this point, you know what's included in these.

A data frame that shows your results and

is ideally self explanatory in showing the data without additional text.

And as always, include a title, legend, north arrow, scale bar,

list of data sources, your name, the day it was published, an inset map,

if applicable and anything else you think makes your map better.

This is a great time to practice new techniques in cartography and

data display.

Play around with the Maplex labeling engine in ArcGIS to make your labels

really clean.

Work with color and patterns to make sure your data is visible at a glance.

Work with the legend options to make your legend extra clear and

anything else you can think of for your map.

There are many ways to draft a better map, and I encourage you to spend the time both

finessing the skills taught in the previous courses, but also exploring and

learning new techniques to make better maps.

If your results aren't easily explain with a single map, feel free to make

a short map series that illustrates your conclusions, or use data driven pages to

make a small map book if your analysis lends itself to that technique.

Similarly, as you make your maps you may notice new things about your results.

This is a great time to polish the conclusions you made in the previous

milestone and update them to reflect what your showing with your maps.

Your maps in the text are complementary to each other.

In most cases neither exists without the other.

And they each serve to help explain the other, and

to provide the viewer a more compete understanding of the analysis and results.

If necessary,

spend some time updating your conclusions to work better with the maps you make.

When you complete your maps, your analysis will be complete as well and

you'll have a new GIS portfolio piece.

I expect that for many of you, this final milestone will take one or

two weeks to complete.

But naturally this varies based on how many maps you make and

how much time you spend finessing your cartography.

For the perfectionists in the course, it can be good to give yourself a time limit.

Making your map better can be an endless task.

There's always something to improve if you allow yourself the time.

At some point, you just have to let go and release your maps.

If any of you have trouble along the way, ask your peers for help in the course

forum, but also explore the GeoNet groups on mapping and cartography.

They may have some tips and techniques that will help you make a better map.

Finally, as always, good luck with your maps and have fun making them.
