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.
The objects are brought together into
collections or families which can be 'owned' by another object, this is a
handy way of collecting together similar objects or ones related to each
other. The hierarchy of objects forms a 'tree' shape with the Site at the
root of the tree and all the many other objects branching out from it.
Objects that can be in a Site Recorder file include:
|
·
Sites and Shared Sites
|
·
Survey Points
|
|
·
Projects
|

Measurements

Site
The Site is the object that represents
the ship, monument or structure being recorded.
Project
The Site
object can contain one or more projects and these are used to collect together sets of Layer objects. Project objects 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
Layer objects. 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 Secto
rs
|
|
·
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
|
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, geo-referenced multibeam echo sounder (MBES) images, scanned
site plans or photomosaics. Image basemaps can also be shown as simple icons on the chart, useful for
associating linked images or video clips on the site plan
Events
Event
objects are used to record things that have happened on site or to the 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.
