Objective. Students organize field data using cloud storage and file-naming conventions, perform data entry and basic computation in a spreadsheet, and compose professional technical emails and reports using industry-standard formatting.
This lesson, its worked examples and its practice questions has not yet been verified by an industry-certified professional or by a certification or approval body. It is a study draft and may contain errors. Do not use it as instructions for work on a job site or on live equipment. Always follow your instructor, your supervising professional, and current official references and regulations.
VoTechWorks program approval and accreditation are still in progress. Credentials are issued only by the certifying bodies named in each program, after their own exams.
Field crews collect raw data every day—GPS coordinates, elevation readings, equipment logs, and site observations. That data is only useful if it is organized, accurate, and communicated clearly to clients, project managers, and regulators. Employers in GIS, surveying, and drone operations expect every technician to manage files systematically, work competently in spreadsheets, and write professional documents. These skills are tested indirectly in NSPS CST and Esri ArcGIS Pro certification work, and they underpin every deliverable you will produce as a professional.
A consistent folder hierarchy prevents data loss and saves hours of searching. The industry convention used in this program follows a three-level structure:
```
ProjectName / YYYY-MM-DD / DataType
```
For example: `OakStreetSurvey / 2025-06-10 / ControlPoints`
Using ISO date format (year-month-day) keeps folders sorted in chronological order automatically. Data-type folders hold raw files in their original format—never overwrite originals. Place processed or edited versions in a clearly labeled subfolder such as `Processed` or `Final`.
Cloud platforms such as Microsoft OneDrive and Google Drive provide version history, which means earlier versions of a file can be recovered if a mistake is made. Always name files descriptively: `OakSt_ControlPts_Raw_2025-06-10.csv` is far safer than `data1.csv`. Avoid spaces in file names; use underscores or hyphens instead, because many GIS applications and command-line tools misread spaces.
Safety and data-security note: Never store files containing client personally identifiable information or sensitive site coordinates on an unsecured personal device or public cloud account without employer authorization. Follow your organization's data-handling policy.
Spreadsheet software (Microsoft Excel or Google Sheets) is the everyday tool for reviewing, cleaning, and summarizing field data before it enters a GIS or survey-adjustment program.
Importing CSV data: A CSV (comma-separated values) file is a plain-text format that nearly every instrument and data collector can export. When you open or import a CSV, verify that column headers match what you expect—point ID, northing, easting, elevation, and description are typical for survey data.
Cleaning common errors:
Summary statistics: Three formulas cover most field-data summaries:
These tell you the elevation range across a site and help identify outliers before data reaches the project file.
Charts: An XY scatter chart (also called an XY plot) graphs easting on the horizontal axis and northing on the vertical axis, giving a rough plan view of point locations. Label axes with units, add a chart title, and include the project name and date in the chart area or caption.
Email is a legal business record. In GIS and surveying, a poorly written email can damage client trust or create confusion about deliverables and deadlines.
A professional technical email includes:
1. Subject line — specific and informative: OakStreetSurvey – Schedule Update Due to Weather
2. Salutation — use the recipient's name and a professional greeting.
3. Opening sentence — state the purpose immediately.
4. Body — one idea per paragraph; plain language; no slang or unexplained jargon.
5. Action item or next steps — tell the reader exactly what happens next and by when.
6. Closing and signature — your full name, job title, company, and contact information.
When notifying a client of a weather delay, acknowledge the inconvenience briefly, explain the reason factually, state the revised schedule clearly, and attach any supporting documents (a revised timeline, for example) with a short note describing each attachment.
A field report documents what happened on site. It protects you, your company, and the client. Standard sections in most survey and GIS field reports are:
| Section | What to include |
|---|---|
| Project name and number | As shown on the contract or work order |
| Date and time | Start and end of field work |
| Weather | Conditions at start and end; note any changes |
| Personnel | Full names and roles of everyone present |
| Equipment used | Instrument make, model, and serial number |
| Observations | Work completed, issues encountered, decisions made |
| Next steps | What remains; who is responsible; target date |
Always export the completed report as a PDF before uploading. PDF preserves formatting across different devices and operating systems, ensuring that what the client or supervisor sees matches what you prepared.
Upload files to the correct cloud folder immediately after completing each task—do not save only to a local drive. Confirm the upload is complete (the file appears in the folder and can be opened) before closing the application. Use the naming convention provided by your instructor, which mirrors professional practice.
Answer each question, then check it. Nothing is recorded; this is your own practice.

Does the school offer financial aid?
No. We don’t offer financial aid because we’re free. No, really: completely free.
Do you offer industry certification?
No. We are not certified yet, so we can’t offer that to students. What we do offer is knowledge and understanding of a trade.
