Site Recorder 4 Objects

< Back    Home    Next >

Site Recorder is a computer program used to record things that exist or happen, most usually in or around an archaeological site. These things are called 'objects' and the programs can contain many different types of objects.

Artefact objects are used to record information about finds and Feature objects are used to record features.  Survey points and measurements can be added and processed creating a framework on which to position the Artefacts and Features on a site plan.  Pictures, video clips and other images can be added then associated with other objects - for example, video of an artefact in-situ can be associated with that artefact.  Other 'spatial' or positioned information can be added for geophysical targets, trenches, drawing frames and wrecks.  Information can be added about the team or staff members as well as about things that have happened on the site.

Objects that can be in a Site Recorder file include:  

·         Sites and Shared Sites

·         Samples

·         Projects

·         Survey Points and Measurements

·         Layers

·         Drawing Frames

·         Artefacts, Features and Sectors

·         Drawing objects

·         Images

·         Image basemaps

·         Events

·         Survey events

·         Sources

·         Targets

·         Wrecks

·         Logbooks

·         Dive Logs and ROV Logs

·         Fix Points

Sites and Shared Sites

The Site is the object that represents the shipwreck, monument or structure being recorded.  

Project

 The Site can contain one or more Projects and these are used to collect together sets of Layers. Projects can be used to record all the work done in a particular excavation season, fieldwork session or survey.
Layer

Each Project can contain a number of Layers and the layers are used to collect together different types of other objects that are associated with each other. The different types of Layers are used to collect together different kinds of objects:

·         Survey layer

Survey points and measurements

·         General layer

Drawing objects such as lines and points, images, Targets, Wrecks and Samples

·         Artefact layer

Artefacts, Features and Sectors

·         Data layer

Data points
Survey Points and Measurements

Survey objects include Survey Points, Measurements and Drawing Frames. Survey Point objects are used to represent the control points and detail points installed on the site. Each individual measurement made between these points are recorded in separate Measurement objects. A number of different measurement types are supported:

·         Distance

A distance measurement between two Survey Points

·         Depth

The depth of a Survey Point

·         Offset

A horizontal or vertical offset measurement between a baseline and a Survey Point

·         Tie

A tie measurement between a baseline and a Survey Point

·         Radial

A distance and direction measured from one Survey Point to another

·         Position

The position of a Survey Point taken from a GPS or acoustic positioning system
Drawing Frames Drawing or planning frames can be added to the chart.  The drawing made on site can be copied into the frame in the computer by tracing over a scanned image of the drawing.  Once done the frame and copied drawing can be positioned on the chart.
Drawing Objects Drawing objects include points, lines (polylines), rectangles, circles and text. Drawing objects can be used to draw such things as maps, trench outlines, contours and the like.
Recording Objects

Archaeology objects include Artefacts, Features and Sectors:

·         Artefact

A find or any kind of object on the site to be recorded

·         Feature

An archaeological recording Feature

·         Sector

Used for defining an area of the site such as a trench
Samples You can record information about environmental samples or samples taken for type testing
Dive Logs Dive Logs and ROV Logs are used to record information about dives and ROV dives.
Contacts Information about people such as archaeologists and divers can be recorded.
Images Image objects are used to record information about any image object including photographs, drawings and video clips.  Images can be linked to other objects such as Artefacts and Dive Logs.
Image Basemaps Image objects are used to show base map pictures on the chart such as side-scan sonar traces or geo-referenced multibeam echo sounder (MBES) images.
Events Event objects are used to record things that have happened on site or to the site.
Survey Events Survey events are used to record geophysical and recording survey work done on site.
Sources Sources such as documents, reports and letters can be recorded along with a link to the source if available in a digital form.
Targets Targets are used to record positions and information about things found during geophysical survey using magnetometers, side-scan sonars, sub-bottom profilers and pulse-induction metal detectors.
Wrecks Information about known wrecks and reported wrecks can be recorded.
Logbooks Logbooks can used to record day-to-day events, ideas, interpretation and thoughts as text documents.
Tracking Site Recorder can be used to display the position of a boat, diver or ROV. Position fixes taken during a survey or during a dive are recorded as Fix Point objects.
